This kit uses a direct competitive ELISA method in microplate coated withOchratoxin A(OA)coupled antigen, adding Ochratoxin A(OA) standard or samples, free Ochratoxin A(OA) and pore strips Pre-coated Ochratoxin A(OA) conjugatedantigen compete against Ochratoxin A(OA) antibody enzyme marker color
with TMB substrate, stop solution added after the color fromblue to yellow, with a microplate reader detection wavelength at 450nm, the sample absorbance valueand Ochratoxin A(OA) content is inversely proportional to the sample throughthestandard curve Ochratoxin A(OA) content.
