Chromogenic Substrates for Factor VIII Assay

Asnail now offers chromogenic substrates (S-2222 and S-2765) for factor VIII assay. The chromogenic assay is recommended for clinical diagnosis of haemophilia, monitoring factor replacement therapies and potency assignment of recombinant factor VIII.

Coagulation factor VIII (FVIII) performs a critical role in the intrinsic blood coagulation pathway. The typical quantitative chromogenic assay for coagulation factor VIII is specified in European Pharmacopoeia, as a two-stage procedure.

Chromogenic Assay of Factor VIII

In this assay, coagulation factor VIII first catalyzes the transformation of factor X into its activated form, factor Xa, which in turn catalyzes the release of pNA from the substrate (S-2222 or S-2765). The potency of coagulation factor VIII is deduced by measuring the chromophore, pNA.

Asnail now offers two chromogenic substrates for this assay.

Chromogenic Substrates for Coagulation Testing

Asnail now offers chromogenic substrates in gram grade for coagulation testing.

These large-quantity chromogenic substrates can be used in chromogenic assay kits.
