BD Pharmingen™ PE Mouse Anti-Human FCRL5 (CD307e)
克隆 509F6 (RUO)

Flow cytometric analysis of FCRL5 (CD307e) expression on transfectants and tonsillar B cells. Left Plot: Non-transfected (Dotted line histogram) and Human FCRL5-transfected (Solid line histogram) P815 cells were surface stained with PE Mouse Anti-Human FCRL5 (CD307e) (Cat. No. 566734) at 0.5 µg/test. Flow cytometric fluorescence histograms showing the expression of FCRL5 (CD307e) on non-transfected or Human FCRL5-transfected P815 cells were derived from gated events with the forward and side light-scatter characteristics of viable cells. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Middle and Right Plots: Tonsil cells were treated with an Fc receptor blocker and stained with APC Mouse Anti-Human CD19 (Cat. No. 561742 or 555415) and either PE Mouse Anti-Human FCRL5 (CD307e) (Cat. No. 566734; Middle Plot) or PE Mouse IgG2a, κ Isotype Control (Cat. No. 554648; Right Plot). Two-color flow cytometric dot plots show the correlated expression patterns of FCRL5 (CD307e) [or Ig isotype control staining] versus Human CD19 for gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry and data analysis were performed using a BD FACSCalibur™ Flow Cytometer System and FlowJo™ software. Data courtesy of Dr. Marco Colonna, Washington University School of Medicine.

- 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.
- 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.

The 509F6 monoclonal antibody specifically binds to Fc receptor-like 5 (FCLR5), a type I transmembrane glycoprotein that is also known as CD307e, FCRH5 (Fc receptor homolog 5) and IRTA2 (immunoglobulin superfamily receptor translocation associated 2). FCRL5 (CD307e) is a member of the Immunoglobulin (Ig) gene superfamily with 9 extracellular Ig domains, an intracellular immunoreceptor tyrosine-based activating motif (ITAM)-like sequence and two intracellular immunoreceptor tyrosine-based inhibitory motif (ITIM)-like sequences. Like other Fc receptor-like proteins, FCRL5 (CD307e) is homologous to FcγR1 (CD64) and binds to immunoglobulins, specifically the IgG isotypes, and it may play a role in the regulatory interactions of immune complexes with B lymphocytes. FCRL5 (CD307e) is differentially expressed in the B cell lineage, with little expression on peripheral blood cells and upregulated expression on plasma cells and some leukemias and lymphomas. mAb 509F6 binds to an epitope within the first 3 Ig domains of FCRL5 and blocks FCRL5's interaction with immune complexes.
