Description
The CBR-IC2/2 monoclonal antibody specifically binds to CD102 which is also known as, intercellular adhesion molecule-2 (ICAM-2/ICAM2). CD102 is a type I transmembrane glycoprotein, member of the immunoglobulin supergene family, with an approximate molecular weight of 55-65 kDa. Its extracellular domain consists of two C2-type immunoglobulin-like subunits. The transmembrane region is 26 residues in size and the intracellular region also has 26 residues. CD102 is expressed on vascular endothelial cells, lymphocytes, monocytes, eosinophils, and platelets, but not on resting neutrophils. It is a ligand for the leukocyte integrin CD11a/CD18, or leukocyte function-associated antigen-1 (LFA-1), and there are reports of CD102 binding to leukocyte integrin CD11b/CD18 (Mac-1). Antibody CBR-IC2/2 blocks the binding of CD102 to leukocyte integrin CD11a/CD18. CD102 plays an important role in lymphocyte recirculation and in providing costimulatory signals in the immune response.
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.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.

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. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. 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.
7. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

8. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.

10. An isotype control should be used at the same concentration as the antibody of interest.

12. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
