Abstract：
:We examined the effects of polysaccharides on t-PA mediated plasminogen activation using single-chain tissue plasminogen activator (sct-PA) and two-chain tissue plasminogen activator (tct-PA). Unfractionated heparin, low molecular weight heparin (LMW heparin) and dextran sulfates enhanced the activation rate of plasminogen by sct-PA about three-fold to six-fold. Chondroitin sulfate C did not enhance the activation. The activation of plasminogen by tct-PA was slightly enhanced by unfractionated heparin, but not by other polysaccharides. Conversion of sct-PA to tct-PA was not stimulated by polysaccharides. SDS-PAGE showed no enhancement of the conversion from sct-PA to tct-PA by plasmin in the presence of polysaccharides. However, the enhancement of sct-PA mediated activation of plasminogen by unfractionated heparin, LMW heparin and dextran sulfates in the presence of aprotinin was shown with SDS-PAGE. It was suggested that unfractionated heparin, LMW heparin and dextran sulfates form complex with sct-PA and plasminogen, and stimulate the conversion of sct-PA to tct-PA.
