Preparation And Storage
Recommended Assay Procedures
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.
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- For U.S. patents that may apply, see bd.com/patents.
- 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.
- 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.
- 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.

- This product may be covered by US Patent No. 7,388,080.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.

- 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.

The 11G7 monoclonal antibody specifically binds to human CD282, which is also known as Toll-like receptor 2 (TLR2). CD282 is expressed on monocytes, granulocytes, and dendritic cells. Toll-like receptors (TLRs) play a critical role in antimicrobial resistance. Moreover, TLRs have been shown to activate a number of signal transduction pathways which lead to the induction of genes involved in host defense. TLRs are type-1 transmembrane receptors characterized by the presence of extracellular leucine-rich repeat and intracellular Toll/IL-1 receptor domains. At least 12 mammalian TLRs have been identified, each recognizing a distinct bacterial or viral pathogen-associated molecular pattern, termed PAMP. Peptidoglycan from Gram-positive bacteria, lipoproteins and lipopeptides from several bacteria, glycophosphatidylinositol, lipoarabinomannan, porins, and zymosan from yeast have been reported to be the ligands for TLR2.
It has been reported that mAb 11G7 inhibits the production of inflammatory cytokines via certain TLR2 ligands including TLR2/TLR1 ligands, lipoarabinomannan and PAM3CSK4. However, 11G7 antibody does not inhibit the production of inflammatory cytokines with zymosan, a TLR2/TLR6 ligand. Please note that this application has not been tested at BD Biosciences Pharmingen.
