Assay principle
ELISA
Microplate
TPO molecules are coated onto the ELISA plate wells. Protein A-Alkaline Phosphatase conjugate constitutes the liquid phase which binds to the TPOAb from the sample bound to the immobilized TPO. The addition of p-nitrophenyl phosphate (pNPP) enables determination of the Protein a-Alkaline phosphatase conjugate bound to the plate. Assay procedure: 15 min at RT / shaking + 15 min at RT / shaking + 15 min at RT in the dark.
