Mouse VEGF ELISA Kit
Mouse VEGF ELISA Kit - Information
The ELISA Genie Mouse VEGF ELISA Kit can assay for Mouse VEGF in the following samples: serum, blood, plasma, cell culture supernatant and other related supernatants and tissues.How our Mouse VEGF ELISA Kits Work?
The ELISA Genie (enzyme-linked immunosorbent assays) assay kits are designed for the quantitative measurement of analytes in a wide variety of samples. As today's scientists demand high quality consistent data for high impact journals, ELISA Genie have developed our range of sensitive, fast and reliable ELISA kit assays to meet and exceed those demands. Our assay kits use a quantitative sandwich ELISA technique and each kit comes with highly specific antibodies pre-coated onto a 96-well microtiter plate.
At ELISA Genie we understand the need for speed! Therefore, we have developed an ultra-fast protocol meaning you achieve your results rapidly. So, once you have prepared and plated your samples, blanks and standards, you simply incubate with a highly specific biotin-conjugated primary antibody and Avidin conjugated to Horseradish Peroxidase (HRP) and incubate for the appropriate length of time. After washing the plate according to the protocol and addition of the TMB (3,3',5,5'-Tetramethylbenzidine) solution, the appearance of a blue colour should be detected due to an enzymatic reaction catalysed by HRP. Next step is the addition of the Stop Solution which terminates the HRP reaction and the blue colour turns yellow with the signal intensity measured on a plate reader at 450nm. The amount of bound Mouse VEGF is proportional to the signal generated by the reaction meaning the kit assay gives you a quantitative measurement of the analyte in your samples.
Mouse VEGF ELISA Kit - Data
Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and UFH. May play a role in increasing vascular permeability during lactation, when increased transport of molecules from the blood is required for efficient milk protein synthesis. Binding to NRP1 receptor initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development (PubMed:26503042).

Sandwich ELISA Double Antibody
This immunoassay kit allows for the in vitro quantitative determination of VEGF(Vascular Endothelial Cell Growth Factor)/VAS/Vasculotropin/VEGFA/VPF/MVCD1/vascular endothelial growth factor A/Vascular permeability factor/VEGF-A concentrations in serum plasma and other biological fluids.
4'C for 6 months
Matrices listed below were spiked with certain level of VEGF(Vascular Endothelial Cell Growth Factor)/VAS/Vasculotropin/VEGFA/VPF/MVCD1/vascular endothelial growth factor A/Vascular permeability factor/VEGF-A and the recovery rates were calculated by comparing the measured value to the expected amount of VEGF(Vascular Endothelial Cell Growth Factor)/VAS/Vasculotropin/VEGFA/VPF/MVCD1/vascular endothelial growth factor A/Vascular permeability factor/VEGF-A in samples.
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of VEGF(Vascular Endothelial Cell Growth Factor)/VAS/Vasculotropin/VEGFA/VPF/MVCD1/vascular endothelial growth factor A/Vascular permeability factor/VEGF-A and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Mouse VEGF ELISA Kit Protocol
The below protocol is a sample protocol for Mouse VEGF ELISA Kit using a biotinylated detection antibody and streptavidin-HRP. Sandwich ELISAs allow for the detection and quantification of an analyte in a sample by using known analyte concentrations as standards and plotting absorbance of known concentrations vs known standard concentrations. This allows the researcher to calculate the amount of Mouse VEGF present in their sample.
Before adding to wells, equilibrate the SABC working solution and TMB substrate for at least 30 min at 37 Â°C. When diluting samples and reagents, they must be mixed completely and evenly. It is recommended to plot a standard curve for each test.
|1.||Set standard, test sample and control (zero) wells on the pre-coated plate respectively, and then, record their positions. It is recommended to measure each standard and sample in duplicate. Wash plate 2 times before adding standard, sample and control (zero) wells!|
|2.||Aliquot 0.1ml standard solutions into the standard wells.|
|3.||Add 0.1 ml of Sample / Standard dilution buffer into the control (zero) well.|
|4.||Add 0.1 ml of properly diluted sample ( Human serum, plasma, tissue homogenates and other biological fluids.) into test sample wells.|
|5.||Seal the plate with a cover and incubate at 37 Â°C for 90 min.|
|6.||Remove the cover and discard the plate content, clap the plate on the absorbent filter papers or other absorbent material. Do NOT let the wells completely dry at any time. Wash plate X2.|
|7.||Add 0.1 ml of Biotin- detection antibody working solution into the above wells (standard, test sample & zero wells). Add the solution at the bottom of each well without touching the side wall.|
|8.||Seal the plate with a cover and incubate at 37Â°C for 60 min.|
|9.||Remove the cover, and wash plate 3 times with Wash buffer. Let wash buffer rest in wells for 1 min between each wash.|
|10.||Add 0.1 ml of SABC working solution into each well, cover the plate and incubate at 37Â°C for 30 min.|
|11.||Remove the cover and wash plate 5 times with Wash buffer, and each time let the wash buffer stay in the wells for 1-2 min.|
|12.||Add 90 Âµl of TMB substrate into each well, cover the plate and incubate at 37Â°C in dark within 10-20 min. (Note: This incubation time is for reference use only, the optimal time should be determined by end user.) And the shades of blue can be seen in the first 3-4 wells (with most concentrated standard solutions), the other wells show no obvious color.|
|13.||Add 50 Âµl of Stop solution into each well and mix thoroughly. The color changes into yellow immediately.|
|14.||Read the O.D. absorbance at 450 nm in a microplate reader immediately after adding the stop solution.|

When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.
If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.
If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.
Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.
Urine & Cerebrospinal Fluid
Collect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.
Cell culture supernatant
Collect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.
Solubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
The preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.
Rinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Collect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.

|UniProt Protein Function:||VEGF: Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth. Defects in VEGFA are a cause of susceptibility to microvascular complications of diabetes type 1 (MVCD1). These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Belongs to the PDGF/VEGF growth factor family. 13 isoforms of the human protein are produced by alternative promoter.|

|NCBI Summary:||This gene is a member of the PDGF/VEGF growth factor family. It encodes a heparin-binding protein, which exists as a disulfide-linked homodimer. This growth factor induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Disruption of this gene in mice resulted in abnormal embryonic blood vessel formation. This gene is upregulated in many known tumors and its expression is correlated with tumor stage and progression. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. There is also evidence for alternative translation initiation from upstream non-AUG (CUG) codons resulting in additional isoforms. A recent study showed that a C-terminally extended isoform is produced by use of an alternative in-frame translation termination codon via a stop codon readthrough mechanism, and that this isoform is antiangiogenic. Expression of some isoforms derived from the AUG start codon is regulated by a small upstream open reading frame, which is located within an internal ribosome entry site.[provided by RefSeq, Nov 2015]|
