The estimation of factor VII in livestock plasma of domestic animals by the use of tripeptide chromogenic substrate.

Abstract

The levels of factor VII in horse, cattle, sheep and pig plasmas were estimated by the use of the synthetic chromogenic substrate, benzoyl-isoleucyl-glutamyl-glycyl-arginyl-p-nitroanilide (S-2222). The highest level of factor VII was observed in the cattle plasma, the lowest one in the plasma of the pig.
