Mouse Somatostatin ELISA Kit - Information

The Mouse Somatostatin ELISA Kit can assay for Mouse Somatostatin in the following samples: serum, blood, plasma, cell culture supernatant and other related supernatants and tissues.

How our Mouse Somatostatin ELISA Kits Work?

The ELISA Genie ELISA (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, We have developed a range of sensitive, fast and reliable ELISA kit assays to meet and exceed those demands.

This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with Mouse Somatostatin. During the reaction, Mouse Somatostatin in the sample or standard competes with a fixed amount of Mouse Somatostatin on the solid phase supporter for sites on the Biotinylated Detection Antibody specific to Mouse Somatostatin. Excess conjugate and unbound sample or standard are washed from the plate, and HRP-Streptavidin(SABC) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Mouse Somatostatin in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Matrices listed below were spiked with certain level of SS/SMST/SOM/SRIF/SST/Growth hormone release-inhibiting factor/SMST/somatostatin/somatostatin-14/somatostatin-28 and the recovery rates were calculated by comparing the measured value to the expected amount of SS/SMST/SOM/SRIF/SST/Growth hormone release-inhibiting factor/SMST/somatostatin/somatostatin-14/somatostatin-28 in samples.

Matrix Recovery range(%) Average(%)
serum(n=5) 86-101 97
EDTA plasma(n=5) 86-103 94
UFH plasma(n=5) 86-102 94

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of SS/SMST/SOM/SRIF/SST/Growth hormone release-inhibiting factor/SMST/somatostatin/somatostatin-14/somatostatin-28 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Mouse Somatostatin ELISA Kit Protocol

The below protocol is a sample protocol for a Mouse Somatostatin ELISA Kit. Competitive ELISA kits allow for the detection and quantification of an analyte in a sample. This Mouse Somatostatin ELISA Kit allows the researcher to calculate the amount of Mouse Somatostatin present in their sample. Before adding to wells, equilibrate the SABC working solution and TMB substrate for at least 30 min at 37 °C. When diluting samples and reagents, they must be mixed completely and evenly. It is recommended to plot a standard curve for each test.

Competitive ELISA Protocol

ELISA Kit Technical Manual

Kit Protocol:

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.Add Sample and Biotin-detection antibody: Add 50µL of Standard, Blank, or Sample per well. The blank well is added with Sample / Standard dilution buffer. Immediately add 50 µL of Biotin-detection antibody working solution to each well. Cover with the Plate sealer we provided. Gently tap the plate to ensure thorough mixing. Incubate for 45minutes at 37°C. (Solutions are added to the bottom of micro ELISA plate well, avoid inside wall touching and foaming to the best of your ability.)
3.Wash: Aspirate each well and wash, repeating the process three times Wash by filling each well with Wash Buffer (approximately 350µL) using a squirt bottle, multi-channel pipette, manifold dispenser or automated washer. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and pat it against thick clean absorbent paper.
4.HRP-Streptavidin Conjugate(SABC): Add 100µL of SABC working solution to each well. Cover with a new Plate sealer. Incubate for 30minutes at 37°C.
5.Wash: Repeat the aspiration/wash process for five times.
6.TMB Substrate: Add 90µL of TMB Substrate to each well. Cover with a new Plate sealer. Incubate for about 10-20 minutes at 37°C. Protect from light. The reaction time can be shortened or extended according to the actual color change, but not more than 30minutes. When apparent gradient appeared in standard wells, you can terminate the reaction.
7.Stop: Add 50µL of Stop Solution to each well. Color turn to yellow immediately. The adding order of stop solution should be as the same as the substrate solution.
8.OD Measurement: Determine the optical density (OD Value) of each well at once, using a microplate reader set to 450 nm. You should open the microplate reader ahead, preheat the instrument, and set the testing parameters.

Sample Preparation

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.

Sample TypeProtocol


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.

Cell lysates

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.

Tissue homogenates

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.

Tissue lysates

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.

Breast Milk

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.
