BD Pharmingen™
C5a Receptor
Human (QC Testing)
Rabbit IgG
Human C5aR sequence aa. 9-29
Flow cytometry (Routinely Tested)
20 µl
Aqueous buffered solution containing BSA and ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

Immunofluorescent Staining and Flow Cytometric Analysis: The C85-4124 antibody is useful for flow cytometric analysis of human C5aR expression. The expression level of human C5aR detected by C85-4124 varies among donors tested. The purified antibody can be used in conjunction with biotinylated goat anti-rabbit Ig and streptavidin-phycoerythrin (Cat. No. 554061) in a three-step staining procedure to amplify immunofluorescent signals.

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  3. Please refer to for technical protocols.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

The rabbit monoclonal antibody C85-4124 reacts with human CD88, which is also known as C5a anaphylatoxin Receptor (C5a receptor, C5aR). CD88 (C5aR) is a seven-transmembrane-spanning G-protein coupled receptor. Its ligand, C5a/C5a-desArg, is the 10 kDa cleavage product of serum protein C5, generated upon Complement System activation. Ligand binding activates the receptor, and mediates lysosomal enzyme release, cytokine and superoxide production, and chemotaxis. Ligand-occupied receptors get internalized (downregulated). Main cellular expression of CD88 (C5aR) includes granulocytes, monocytes, dendritic cells, astrocytes, and microglia. The extracellular, N-terminal 9-29 amino acids of the human C5aR sequence was used as an immunogen to generate C85-4124 monoclonal antibody from rabbits.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
