A low molecular weight antiplasmin has been detected in human blood platelets. The antiplasmin is dialysable and a similar material is present in normal plasma. A simple method for rapid isolation of the antiplasmin based on ultrafiltration is described. The inhibition of plasmin by these materials under different conditions has been studied. In the(More)
Fibrin-stabilizing factor is known to cross-link fibrin monomers. This study was undertaken to explore whether a similar interaction might occur between actin and fibrin. Purified actin and fibrinogen were labeled with 131I and 125I, respectively. The interaction of actin and fibrin, under different conditions, was evaluated by gel electrophoresis. The data(More)
For the dozens of visitors to the 2012 East Bay Mini Maker Faire, many remarkable experiences were ripe for the taking. They could share in hands-on activities while attending a working group on outdoor mosaics, observing a robot-making demonstration, or sitting in on a make-your-own ter-rarium class. The activity in Studio One was no different: the energy(More)
Plasma from patients with thrombotic thrombocytopenic purpura (TTP) caused the aggregation of autologous and homologous platelets, and effect which was inhibited by normal plasma. IgG purified from seven normal adults at a concentration of 0.7 mg/ml completely inhibited the platelet aggregation induced by plasma obtained from two TTP patients with active(More)
Plasma from patients with thrombotic thrombocytopenic purpura (TTP) caused the aggregation of washed human platelets, which was inhibited by preincubation with normal plasma. Using salt fractionation, ion exchange chromatography, and preparative agarose gel electrophoresis, we purified a protein from normal plasma which inhibited the platelet aggregation(More)
