Summary
Thrombin, incubated with 2,3-diphosphoglycerate (150 nmol 2,3-DPG/1 NIH thrombin unit) lost up to 70% of its clotting activity, whereas the esterase activity remained unchanged. No fibrinopeptide release by thrombin was observed in the presence of 2,3-DPG. The fibrin polymerization was normal. By chromatography on Amberlite IRC-50, α-thrombin was eluted at pH 8.0. In presence of 2,3-DPG, α-thrombin was not eluted. Likely, 2,3-DPG can interfere with thrombin.
