| Description : |
Derived from proteolytic degradation of complement C5, C5 anaphylatoxin is a mediator of local inflammatory process. C5 precursor is first processed by the removal of 4 basic residues, forming two chains, beta and alpha, linked by a disulfide bond. C5 convertase activates C5 by cleaving the alpha chain, releasing C5a anaphylatoxin and generating C5b (beta chain + alpha' chain). Activation of C5 by a C5 convertase initiates the spontaneous assembly of the late complement components, C5-C9, into the membrane attack complex. C5b has a transient binding site for C6. The C5b-C6 complex is the foundation upon which the lytic complex is assembled. The C5a anaphylatoxin interacts with C5AR1 and tick complement inhibitor. C5a is also a potent chemokine which stimulates the locomotion of polymorphonuclear leukocytes and directs their migration toward sites of inflammation. |
| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant. |
| Specificity : |
Protein Ratio: Passed as determined by the HABA assay/binding ELISA. |
| Bio-activity : |
Immobilized Biotinylated Human Complement C5, His, Avi tag at 1 μg/mL (100 μL/well) on streptavidin precoated (0.5 μg/well) plate can bind Monoclonal Anti-Human C5a Human Antibody, Human IgG1 with a linear range of 0.1-3 ng/mL. |
| Molecular Mass : |
The mature form of Complement C5 is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. Each α and β chain has a calculated MW of 73.9 kDa (β chain) and 116.1 kDa (α chain). The protein migrates as 75 kDa, 120 kDa and 200 kDa under reducing (R) condition, and 200 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation. |
| Purity : |
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS. |
| Storage : |
This product is stable after storage at: -20 to -70 centigrade for 12 months in lyophilized state; -70 centigrade for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents. |
