<p>Novel thrombin-binding substances (A) and (B) are disclosed. The thrombin-binding substances have the following characteristics: (a) molecular weight: Thrombin-binding substance (A): 90,000-92,000 under reduced conditions 55,000-58,000 under unreduced conditions Thrombin-binding substance (B): 98,000-105,000 under reduced conditions 60,000-65,000 under unreduced conditions (b) isoelectric point: Thrombin-binding substance (A): pH 6.0-6.8 Thrombin-binding substance (B): pH 5.8-6.5 (c) affinity: strong affinity to thrombin (d) activity: (1) capable of promoting the thrombin catalyzed activation of protein C (2) prolongs clotting time; and (e) stability: stable to denaturing agents (sodium dodecylsulfate and urea). The thrombin-binding substances are useful as a medicine for curing thrombosis.</p> |
