Human Annexin V/ANXA5 Protein

Recombinant Human Annexin V/ANXA5 Protein is expressed from E.coli without tag.It contains Ala2-Asp320. Propidium iodide (PI) is widely used in conjunction with Annexin V to determine if cells are viable, apoptotic, or necrotic through differences in plasma membrane integrity and permeability. The Annexin V/PI protocol is a commonly used approach for studying apoptotic cells. PI is used more often than other nuclear stains because it is economical, stable and a good indicator of cell viability, based on its capacity to exclude dye in living cells.
