Recombinant Human Complement Component C5a (Catalog # 2037-C5) induces N-acetyl-beta -D-glucosa-minidase release in the dibutyryl cyclic-AMP differentiated U937 human histiocytic lymphoma cell line in a dose-dependent manner (orange line). N-Acetyl-beta -D-Glucosaminidase Release elicited by Recombinant Human Complement Component C5a (10 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human Complement Component C5a R1 Monoclonal Antibody (Catalog # MAB3648). The ND₅₀ is typically 2-10 µg/mL in the presence of cytochalasin-B.

Applications for Human Complement Component C5aR1 Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Flow Cytometry

2.5 µg/10⁶ cells
Sample: Human peripheral blood granulocytes

Neutralization

Measured by its ability to neutralize Complement Component C5a-induced N-acetyl-beta -D-glucosaminidase release in the dibutyryl cyclic-AMP differentiated U937 human histiocytic lymphoma cell line. Gerard, NP and Gerard, C. (1990) Biochemistry 29:9274. The Neutralization Dose (ND₅₀) is typically 2-10 µg/mL in the presence of 10 ng/mL Recombinant Human Complement Component C5a and cytochalasin‑B.

Background: Complement Component C5aR1

Complement Component C5a R1 (C5aR1), also known as C5a ligand and CD88, is a 7TM protein expressed on myeloid, endothelial, epithelial, and smooth muscle cells. C5aR binds the activated complement anaphylatoxin C5a. In established allergic environments, this triggers neutrophil and eosinophil chemotaxis and the release of proinflammatory mediators. In contrast, C5aR1/C5a interactions are protective during allergen sensitization. Human C5aR1 shares 66% amino acid sequence identity with mouse and rat C5aR.
