Multi-Species Vitamin D3 ELISA Kit AR Then a biotinylated detection antibody

Then a biotinylated detection antibody specific for Human MUC5AC and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated

The concentration of Universal OT in tested samples can be calculated by comparing the OD of the samples to the standard curve

only those wells that contain Human PCT and HRP-conjugated antibody will exhibit a change in color

This Fibroblast Growth Factor 21 ELISA kit uses the Sandwich-ELISA principle

Multi-Species Vitamin D3 ELISA Kit AR Then a biotinylated detection antibodyThe Vitamin D3 ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Universal VD3. During the reaction, Universal VD3 in the sample or standard competes with a fixed amount of Universal VD3 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal VD3. Excess conjugate and unbound sample or standard are washed away, and Avidin Horseradish Peroxidase
