What is Plasma Membrane Isolation?
The plasma membrane is a dynamic structure that regulates the movement of molecules in and out of cells, plays a key role in signal transduction, and provides structural integrity. Isolating this membrane is essential for studying membrane-associated proteins, lipid composition, and receptor-ligand interactions.
