Preparation And Storage

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 with BD Horizon BV711 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. 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.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

11G7

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.

The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm.  BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor® 700-like dyes (eg, 712/20-nm filter).  Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor® 700 and PerCP-Cy5.5 detectors.  However, the spillover can be corrected through compensation as with any other dye combination.

BV711
The BD Horizon Brilliant Violet™ 711 (BV711) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 407-nm and an acceptor dye with an emission maximum (Em Max) at 713-nm. BV711, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 710-nm (e.g., a 712/20-nm bandpass filter). The acceptor dye can be excited by the Red (628–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
