hydatid cyst fluid has been used as a source of antigen for the serodiagnosis of echinococcus granulosus infection. due to cross-reactions with antigens shared by other helminthes, the specific antigen from hydatid cyst fluid was purified by many workers. we used a relatively simple technique for purification of specific antigen from sheep hydatid cyst fluid. isopycnic ultracentrifugation with ...

Snake venoms contain a rich variety of factors which affect blood coagulation. There have been few reports on the anticoagulant activity of the venom of different cobras, but no such observations have been made on the Iranian cobra, although a procoagulant factor has been described. In this study an anticoagulant factor has been purified from the venom of Naja naja oxiana using gel filtrat...

The Sec6/8 (exocyst) complex is an essential component of the exocytic apparatus and plays an evolutionarily conserved role in polarized membrane growth. During development of epithelial cell polarity, this cytosolic protein complex is recruited to plasma membrane sites of cell-cell contact, where it facilitates exocytosis to the lateral membrane domain. However, the identity of membrane bindin...

Density gradient ultracentrifugation of low density lipoproteins (LDL) from 12 normal subjects showed multiple, distinct isopycnic bands. Densitometric scanning of the gradient tubes revealed that each band could be assigned to one of four density intervals and that the boundaries of these intervals were consistent among all the subjects. Analytic ultracentrifuge flotation (S(f)(0)) rates were ...
