  • HY-P78247
    Complement C3 Protein, Mouse (HEK293, His)

    Complement C3; HSE-MSF; C3; CPAMD1; AHUS5; ARMD9; ASP; C3a; C3b; HEL-S-62p

    		 Mouse HEK293
    Complement C3 protein activates the complement system, playing a central role in both classical and alternative pathways. C3b binds covalently to cell surface carbohydrates or immune aggregates, while C3a acts as an inflammatory mediator, inducing neutrophil chemoattraction and promoting smooth muscle contraction, increased vascular permeability, and histamine release. The shorter isoform of C3a stimulates B-cells. Complement C3 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Complement C3 protein, expressed by HEK293 , with C-His labeled tag. The total length of Complement C3 Protein, Mouse (HEK293, His) is 1639 a.a., with molecular weight of 65-68 kDa & 110-115 kDa & 165-180 kDa, respectively.

    Complement C3/C3 Protein, Bovine (His-SUMO)

    C3Complement C3; Complement C3b alpha' chain; Complement C3c alpha' chain fragment 1; Complement C3dg fragment; Complement C3g fragment; Complement C3d fragment; Complement C3f fragment; Complement C3c alpha' chain fragment 2]

    		 Bovine E. coli
    Complement C3/C3 proteins play a key role in initiating the complement system, serving as substrates for C3 convertase in both the classical and alternative pathways. Upon activation, C3 undergoes proteolytic cleavage, yielding C3b, which is covalently bound to surface or immune aggregates. Complement C3/C3 Protein, Bovine (His-SUMO) is the recombinant bovine-derived Complement C3/C3 protein, expressed by E. coli , with N-His, N-SUMO labeled tag. The total length of Complement C3/C3 Protein, Bovine (His-SUMO) is 207 a.a., with molecular weight of ~44 kDa.
