Complement C3 Protein, Cynomolgus (HEK293, His)

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.

C3 assumes a pivotal role in the initiation of the complement system, and its processing by C3 convertase constitutes a central reaction in both classical and alternative complement pathways. Following activation, C3b has the capacity to covalently bind to cell surface carbohydrates or immune aggregates through its reactive thioester. Concurrently, the anaphylatoxin C3a, derived from the proteolytic degradation of complement C3, serves as a mediator in local inflammatory processes. In instances of chronic inflammation, C3a acts as a chemoattractant for neutrophils, inducing smooth muscle contraction, increasing vascular permeability, and triggering histamine release from mast cells and basophilic leukocytes.

Measured by its ability to enhance IL-6 secretion by THP 1 human acute monocytic leukemia cells. The ED₅₀ for this effect is 0.5837 μg/mL, corresponding to a specific activity is 1713.209 U/mg.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
