Also acts as a decay-accelerating factor, preventing the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade. Plays a crucial role in early embryonic development by maintaining fetomaternal tolerance. Also acts as a costimulatory factor for T-cells which favors IL-4 secretion.Reference: "The murine complement receptor gene family: III.

Immunol. 144:1988-1996(1990)Purity: Greater than 85% as determined by SDS-PAGE.Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
