Preparation and Storage
推奨アッセイ手順
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.

The hC3aRZ8 monoclonal antibody specifically binds to the human C3a Receptor (C3aR). C3aR is a seven-transmembrane glycoprotein, G-protein-coupled receptor that is the specific receptor for C3a anaphylatoxin. The C3aR consists of 482 amino acids forming a single polypeptide chain that is encoded by the C3AR1 gene located on chromosome 12 (location 12p13.31). C3aR are expressed by eosinophils, basophils, neutrophils, dendritic cells, monocytes, macrophages, endothelial cells and some T cells. C3a is a bioactive cleavage product released from Complement Component 3 (C3) during complement activation. C3a plays a role in a variety of cellular immune responses as well as being a potent pro-inflammatory agent. In response to bound C3a, this receptor stimulates cellular responses including chemotaxis, granule enzyme release and superoxide anion production and causes increased vascular permeability. In vivo, C3a production can initiate, contribute to, or exacerbate the inflammatory reactions seen in gram-negative bacterial sepsis, trauma, ARDS, ischemic heart disease, post-dialysis syndrome, and several autoimmune diseases including rheumatoid arthritis, lupus erythematosus, and acute glomerulonephritis.
