Frequently Asked Questions Live Chat and Frequently Asked Questions  are available for this Product.
Analysis Note Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard, Lot K.
  The NIH assay procedure uses 0.2 mL of diluted plasma (1:1 with saline) as a substrate and 0.1 mL of thrombin sample (stabilized in a 1% buffered albumin solution) based on a modification of the method of Biggs. Only clotting times in the range of 15-25 seconds are used for determining thrombin concentrations.
Biochem/physiol Actions Serine protease that selectively cleaves Arg-Gly bonds in fibrinogen to form fibrin and fibrinopeptides A and B.
