产品描述 | C3a (70-77) TFA (Complement 3a (70-77) TFA) is an octapeptide corresponding to the COOH terminus of C3a, exhibits the specificity and 1 to 2% biologic activities of C3a[1][2]. The direct interaction of C3a(70-77) with human mononuclear leukocytes in culture results in a concentration-dependent inhibition of the generation of LIF evoked by mitogens and by the antigen SK-SD[1]. C3a (70-77) induces histamine release and degranulation of rat mast cells, promotes contraction of guinea pig ileal tissue, and enhances vascular permeability in human skin. C3a (70-77) selectively desensitizes ileal smooth muscle to C3a but not to human C5a, a related anaphylatoxin. The cross-desensitization indicates a specific interaction of C3a (70-77) with cellular C3a binding sites[2]. [1]. Payan DG, et al. Modulation of human lymphocyte function by C3a and C3a(70-77).
