蛋白结构(Molecular Characterization)

Complement C3 Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 186.8 kDa. The protein migrates as 80 kDa and 120-130 kDa and 200 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Protocol

 

背景(Background)

C3 is the major complement component serum. It is mainly synthesized by macrophages and liver. C3 plays a central role in the activation of the complement system. Its processing by C3 convertase is the central reaction in both classical and alternative complement pathways. It is cleaved into two fragments, C3a and C3b. C3a anaphylatoxin is a mediator of local inflammatory process. In chronic inflammation, acts as a chemoattractant for neutrophils. After activation C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes.
