Human C3a Protein, Natural - 50 µg (CAT#: CB-P281-AB) Datasheet

Product Type
C3 is the third part of the complement system and plays a central role in the complement cascade. In this key molecule, the three ways of compliment activation converge. Cleavage of the key complement component C3 leads to a set of effector molecules with multiple biological functions. The cleavage product C3b promotes complement culture and subsequent formation of membrane attack complexes. C3a, the small (about 10 kDa) lysate has allergic and immunomodulatory properties. It works through a specific receptor (C3aR), which belongs to the family of G protein coupled receptors. The expression of C3aR- in many cell types has been reported, including bone marrow cells and non-bone marrow cells. It has been demonstrated that the expression of C3aR on hematopoietic stem/progenitor cells can promote the transport/homing of these cells to BM. The involvement of C3aR on DC and T cells has been shown to up-regulate the functions of these cells.

Functional studies
Application Notes
For functional studies, the in vitro dilution must be optimized in the user's experimental setting.
Storage Instructions
Product should be stored at -80°C. Repeated freeze and thaw cycles will cause loss of activity. Use C5 protein within 34 hours after thawing and keep on ice. Remainder amounts should be aliquoted and immediately re-freezed for future use. Aliquots should never be thawed more than once. Under recommended storage conditions, product is stable for at least one year.
