Plasma Membrane. All living cells, prokaryotic and eukaryotic, have a plasma membrane that encloses their contents and serves as a semi-porous barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from entering.lasma Membrane.

Proteins Present in the T-Tubule Membrane. The function of the t-tubules depends not only on their structure but also on the proteins within, and adjacent to, the t-tubule membrane. Immunohistochemical techniques have been widely used to investigate the location of proteins within cardiac ventricular myocytes.ata from normal cells suggest that the major difference between the t-tubule and surface membranes is the concentration of Ca 2+ -handling proteins at the t-tubules. Therefore, in this section, we will concentrate on these proteins.
