We examined binding and internalization (endocytosis) of PAI-1 and Vn by Dami cells using biotinylated analogs (b-PAI-1 and b- ... Cells were incubated at 4 degrees C or 37 degrees C and endocytosis of b-Vn was shown by probing electrophoretically ... The two possible sources for their biosynthetic origin are endogenous synthesis in megakaryocytes or endocytosis from plasma. ... of PAI-1 in Dami cell storage granules is due to endogenous synthesis and that the accumulation of Vn is due to endocytosis of ...
