The plasma membrane is a selectively permeable phospholipid bilayer that surrounds the cytoplasm of cells, separating the intracellular components from the extracellular environment. It is primarily composed of proteins and lipids and is instrumental in signaling pathways. The plasma membrane also anchors the cytoskeleton, giving the cell shape, and serves as an attachment point for the extracellular matrix and surrounding cells to help them group together to form tissues.
Plasma membrane marker antibodies detect proteins specific to the plasma membrane and can aid in the study of the morphology and functions of the plasma membrane. Plasma membrane marker antibodies can also help elucidate the role a protein may play in tasks that are centered in the plasma membrane such as transporter, receptor, anchor, enzyme, etc.
Each Invitrogen plasma membrane marker antibody is validated for use in applications such as ELISA, western blot, flow cytometry, immunofluorescence, immunohistochemistry, immunocytochemistry, and immunoprecipitation.
