Human A beta1-40 (Amyloid Beta Peptide 1-40) ELISA Kit (HUES01733)
Human A beta1-40 (Amyloid Beta Peptide 1-40) ELISA Kit
This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human A beta1-40 . Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human A beta1-40 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human A beta1-40, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human A beta1-40. The concentration of Human A beta1-40 in samples can be calculated by comparing the OD of the samples to the standard curve.
|Detection Range||15.63-1000 pg/mL|
|Sample Volume Required Per Well||100uL|
|Sample Type||Serum, plasma and other biological fluids|
This kit recognizes Human A beta1-40 in samples. No significant cross-reactivity or interference between Human A beta1-40 and analogues was observed.
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human A beta1-40 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human A beta1-40 were tested on 3 different plates, 20 replicates in each plate.

The recovery of Human A beta1-40 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
|Sample Type||Range (%)||Average Recovery (%)|
|EDTA plasma (n=5)||85-96||91|
|Cell culture media (n=5)||92-108||100|
Samples were spiked with high concentrations of Human A beta1-40 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
