974 Platelet Membrane Glycoproteins
Glycoproteins I Ib / I I Ia form a Ca2+-dependent complex that functions as the fibrinogen receptor on human platelets (1). Several reports have indicated that this fibrinogen receptor is also expressed on the surface of human monocytes (2-4). Of three monoclonal antibodies directed against platelet I Ib/ I I Ia , two were reported to give a positive reaction with monocytes as well (4). Other i...
متن کاملEffect of morin on glycoproteins and membrane bound enzymes in streptozotocin-induced diabetic rats
This study investigated the effect of morin on membrane bound enzymes and glycoproteins in normal and streptozotocin (STZ)-induced diabetic Wistar rats. Diabetes was induced in rats by an intraperitoneal injection of STZ, dissolved in citrate buffer (0.01 M, pH 4.5) and injected to overnight fasted rats with a dose of STZ 50 mg/kg. Morin was dissolved in carboxy methyl cellulose (CMC) at a dose...
متن کاملDolichol phosphate, a coenzyme in the glycosylation of animal membrane-bound glycoproteins.
The last few years have seen a tremendous increase in interest in, and understanding of, the biochemistry of membranes. One membrane-associated activity is the catalysis of the glycosylation of complex polysaccharides and glycoproteins. The formation of bacterial wall polysaccharides by preparations of plasma membrane has been studied extensively, and the role of undecaprenol phosphate as a lip...
متن کاملGlycoproteins of the lysosomal membrane
Three glycoprotein antigens (120, 100, and 80 kD) were detected by mono- and/or polyclonal antibodies generated by immunization with highly purified rat liver lysosomal membranes. All of the antigens were judged to be integral membrane proteins based on the binding of Triton X-114. By immunofluorescence on normal rat kidney cells, a mouse monoclonal antibody to the 120-kD antigen co-stained wit...
متن کاملPlatelet membrane glycoproteins: historical perspectives
The function of blood platelets to prevent blood loss at injured sites in the vasculature depends largely on their capacity to adhere, aggregate, promote coagulation and secrete factors that induce vasoconstriction and recruit inflammatory cells. Produced in large numbers from megakaryocytes, platelets enter the circulation for 7–10 days primed to fulfill their hemostatic function. By 1970, tho...
