BV421 Mouse Anti-Human Fcµ Receptor
BV421 Mouse Anti-Human Fcµ Receptor

Multicolor flow cytometric analysis of Fcμ Receptor expression on human peripheral blood mononuclear cells. Peripheral blood mononuclear cells were stained with BD Horizon™ BV421 Mouse Anti-Human Fcμ Receptor (Cat. No. 564714), FITC Mouse Anti-Human CD3 (Cat. No. 555332/561806/561807), and APC Mouse Anti-Human CD11b (Cat. No. 550019/561015) antibodies. Two-color flow cytometric contour plots showing the correlated expression patterns of CD3 (Left Panel) or CD11b (Right Panel) versus Fcμ Receptor were derived from gated events with the forward and side light-scatter characteristics of viable leucocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

HM14-1

The HM14-1 monoclonal antibody specifically binds to the FAIM3-encoded high affinity receptor for IgM (also known as, Fcµ Receptor, FcμR, Fc mu receptor, Immunoglobulin mu Fc receptor, FcmR, IgM Fc receptor). The FcμR is a type 1 transmembrane glycoprotein that contains an extracellular Ig-like domain with sequence similarities to Fcα/μR and pIgR. It is likewise known as Fas apoptotic inhibitory molecule 3, TOSO or Regulator of Fas-induced apoptosis Toso based on its capacity to counter apoptosis mediated by Fas/CD95 (or TNF) in some experimental model systems. FcμRs are expressed by B cells, CD4+ T cells, CD8+ T cells, and NK cells and are highly expressed on Chronic Lymphocytic Leukemia cells. FcμRs may play roles in cellular activation, antigen presentation and IgM-dependent cell-mediated cytotoxicity. The relatively long cytoplasmic tail of FcμR contains several conserved tyrosine and serine residues. These get phosphorylated after FcμR ligation with IgM immune complexes and may initiate signaling responses. Lymphocyte FcμRs can mediate the internalization of IgM-bound antigens including microbial and viral antigens. This in turn may cause cellular activation due to subsequent antigen processing and exposure of activating ligands to intracellular receptors including Toll-like receptors. The HM7-10 antibody, a related FcμR-specific antibody, reportedly recognizes an epitope near the IgM ligand binding site of the FcμR whereas the HM14-1 antibody does not.

The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
