Complement C5 Protein, Human (Biotinylated, HEK293, His-Avi)

Customer Review

Based on 1 Customer Validation

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, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Complement C5 protein, expressed by HEK293, with C-Avi;C-hFc labeled tag.

Biological Activity

Description

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, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Complement C5 protein, expressed by HEK293, with C-Avi;C-hFc labeled tag.

Background

Upon activation by a C5 convertase, Complement C5 initiates the spontaneous assembly of the late complement components, C5-C9, forming the membrane attack complex. The transient binding site for C6 on C5b is crucial for the foundation of the lytic complex. The proteolytic degradation of complement C5 produces C5a anaphylatoxin, a mediator of local inflammatory processes. C5a interacts with its receptor C5AR1, triggering diverse responses such as intracellular calcium release, smooth muscle contraction, increased vascular permeability, and histamine release from mast cells and basophilic leukocytes. Acting as a potent chemokine, C5a stimulates the locomotion of polymorphonuclear leukocytes and guides their migration toward sites of inflammation, contributing to the orchestration of immune responses.

Verified Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized Biotinylated Human Complement C5, His,Avitag 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 the EC50 of 1.69 ng/mL.
