  • HY-P7862
    Complement C3/C3a Protein, Human

    rHuComplement C3/C3a; Complement Component C3a; C3a; Anaphylatoxin

    Human E. coli
    Complement C3/C3a proteins play a key role in initiating the complement system through processing by C3 convertase in the classical and alternative pathways. Upon activation, C3b covalently binds to the surface, while C3a (anaphylatoxin produced by proteolysis of C3) mediates local inflammation. Complement C3/C3a Protein, Human is the recombinant human-derived Complement C3/C3a protein, expressed by E. coli , with tag free. The total length of Complement C3/C3a Protein, Human is 77 a.a., with molecular weight of ~13.0 kDa.
  • HY-P7863
    Complement C3/C3a Protein, Mouse

    rMuComplement C3/C3a; Complement Component C3a; Anaphylatoxin; C3a

    Mouse E. coli
    Complement C3/C3a 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/C3a Protein, Mouse is the recombinant mouse-derived Complement C3/C3a protein, expressed by E. coli , with tag free. The total length of Complement C3/C3a Protein, Mouse is 78 a.a., with molecular weight of 9-14 kDa.
  • 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.
  • HY-P78595
    Complement C5/C5a Protein, Cynomolgus

    C5a; Complement Component 5a

    Cynomolgus E. coli
    Complement C5 is activated by C5 convertase, inducing C5-C9 assembly to form the membrane attack complex. The transient C6 binding site on C5b is critical for the formation of the cleavage complex. Complement C5/C5a Protein, Cynomolgus is the recombinant cynomolgus-derived Complement C5/C5a protein, expressed by E. coli , with tag free. The total length of Complement C5/C5a Protein, Cynomolgus is 74 a.a., with molecular weight of ~11 kDa.
  • HY-P75332
    Complement C3 Protein, Cynomolgus (HEK293, His)

    Anaphylatoxin; C3; Complement Component C3a

    Cynomolgus HEK293
    Complement C3 proteins play a key role in initiating the complement system through processing by C3 convertase in the classical and alternative pathways. Upon activation, C3b covalently binds to the surface, while C3a (anaphylatoxin produced by proteolysis of C3) mediates local inflammation. Complement C3 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived Complement C3 protein, expressed by HEK293 , with C-His labeled tag. The total length of Complement C3 Protein, Cynomolgus (HEK293, His) is 1641 a.a., with molecular weight of ~186.40 kDa.
  • HY-P71552
    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 ~39.5 kDa.
