25-OHVD3 ELISA Kit

Storage Instruction:Store the kit at 4°C.
Description:
This immunoassay kit allows for the in vitro quantitative determination of felis AChR concentrations in cell culture supernates, serum, plasma and other biological fluids.
The microtiter plate provided in this kit has been pre-coated with antigen. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antigen and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain AChRab, biotin-conjugated antigen and enzyme-conjugated Avidin will exhibit a change in color. 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 ± 2 nm. The concentration of AChRab in the samples is then determined by comparing the O.D. of the samples to the standard curve.
