Rat GC(Glucagon) ELISA Kit

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with GC. During the reaction, GC in the sample or standard competes with a fixed amount of GC on the solid phase supporter for sites on the Biotinylated Detection Ab specific to GC. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of GC in tested samples can be calculated by comparing the OD of the samples to the standard curve.

An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the components separately according to the following conditions once the kit is received.

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

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