The membrane potential of human platelets.
The membrane potential of the human platelet was investigated using the membrane potential probes 3,3'-dipropyl-2,2'-thiadicarbocyanine iodide and tritiated triphenylmethylphosphonium bromide. The membrane potential in physiologic buffer was estimated to be 52-60 mV inside negative. The membrane was depolarized when extracellular potassium or hydrogen ion concentrations were increased. Changes ...
متن کاملMembrane Protein from Human Platelets
Incubation of intact but not disrupted platelets with thrombin resulted in the release of thrombin-sensitive protein from the platelet membrane. The rapid release of this protein (Ti < 15 sec) at low concentrations of thrombin suggested that removal of thrombin-sensitive protein from the platelet membrane is an integral part of the platelet release reaction. This hypothesis is supported by the ...
متن کاملIdentification of membrane proteins mediating the interaction of human platelets
Membrane glycoproteins that mediate platelet-platelet interactions were investigated by identifying those associated with the cytoskeletal structures from aggregated platelets. The cytoskeletal structures from washed platelets, thrombin-activated platelets (platelets incubated with thrombin in the presence of mM EDTA to prevent aggregation) and thrombin- aggregated platelets (platelets activate...
متن کاملThe Effect of Gnidilatimonoein from Daphne mucronata, on the Adhesive Property of Human Platelets
The adhesive interaction between tumor cells and the host cells or the extracellular matrix plays a crucial role in tumor metastasis. To evaluate the mediation of cell adhesion by Daphne mucronata, an anti-cancer medicinal plant in Iranian folk medicine, the adhesion of thrombin activated human platelets to the cultured monocytes or HL-60 cells was investigated under the effect of the plant ext...
متن کاملPotatoes: Source of Laboratory Reagent for Human Platelets Research
Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...
