Test principle This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse LEP. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Mouse LEP are added to the micro ELISA plate wells. Mouse LEP in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Mouse LEP. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The OD value is proportional to the concentration of Mouse LEP. The concentration of Mouse LEP in the samples is then determined by comparing the OD of the samples to the standard curve.

Technical Data

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.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level were tested on 3 different plates, 20 replicates in each plate, respectively.

Rate of recovery

The recovery of spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range(%) Average Recovery(%)
Serum (n=8) 83-95 89
EDTA plasma (n=8) 95-107 101
Cell culture media (n=8) 82-94 88
Linear

Samples were spiked with high concentrations of target proteins and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
