Recombinant Human Complement C5(C5),partial

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 -20C/-80C. The shelf life of lyophilized form is 12 months at -20C/-80C.

Tris-based buffer, 50% glycerol

Activation of C5 by a C5 convertase initiates the spontaneous assbly of the late complent components, C5-C9, into the mbrane attack complex. C5b has a transient binding site for C6. The C5b-C6 complex is the foundation upon which the lytic complex is assbled.Derived from proteolytic degradation of complent C5, C5 anaphylatoxin is a mediator of local inflammatory process. Binding to the receptor C5AR1 induces a variety of responses including intracellular calcium release, contraction of smooth muscle, increased vascular permeability, and histamine release from mast cells and basophilic leukocytes. C5a is also a potent chokine which stimulates the locomotion of polymorphonuclear leukocytes and directs their migration toward sites of inflammation.

Repeated freezing and thawing is not recommended. Store working aliquots at 4C for up to one week.
