When a drug permeates a cell, it must obviously traverse the cellular plasma membrane.
Membrane microparticles are shed from the plasma membrane of most eukaryotic cells when these cells were undergone activation or apoptosis, and released into the extracellular environment.
The nuclei removed by these techniques are not surrounded by a narrow rim of cytoplasm and a plasma membrane.
Thus, we conclude that the sites of H_2O_2 generation induced by ABA in guard cells are plasma membrane and chloroplasts.
Many glycoproteins of lower and higher eucaryotes are attached to the plasma membrane by means of a glycosylphosphatidylinositol(GPI) .
Protoplast The protoplasm and plasma membrane of a cell after removal of the cell wall, where present. This can be achieved by physical means or by enzymic digestion.
It is concluded that high extracellular calcium can injure renal tubular cells, but not by the way of destroying the plasma membrane integrity.
Over the years, it has frequently been assumed that washing the cells with buffer after incubation causes desorption of peptide associated with the plasma membrane.
Any of several plant glycoproteins that bind to specific carbohydrate groups on the plasma membrane of cells, used in the laboratory to stimulate proliferation of lymphocytes and to agglutinate red blood cells.
