VD (Vitamin D) ELISA Kit Packaging:48 wells Substrate solution is then added

Substrate solution is then added and color develops in proportion to the amount of Rat HPSE

And then biotinylated Human IRS-2 Antibody is added and binds to IRS-2 in the sample

The concentration of Goat IL-12p40 in the samples is then determined by comparing the OD of the samples to the standard curve

The Human GDF2 (Growth Differentiation Factor 2) ELISA kit uses the Sandwich-ELISA principle

VD (Vitamin D) ELISA Kit Packaging:48 wells Substrate solution is then addedThe VD (Vitamin D) ELISA immunoassay kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with VD. Standards or samples are added to the appropriate micro ELISA plate wells then with a biotin conjugated antibody specific to VD. Next,Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme substrate reaction is
