Clone 5E7

(RUO)

Two color flow cytometric analysis of Blimp-1 expression in activated mouse splenocytes. Mouse splenic leucocytes were stimulated for 3 days with lipopolysaccharide and stained with FITC Rat Anti-Mouse CD45R/B220 antibody (Cat. No. 553088/553087/561877). The cells were subsequently fixed and permeabilized with the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725) and stained with either PE Rat IgG2a, κ Isotype Control (Cat. No. 554689; Left Panel) or PE Rat Anti-Mouse Blimp-1 antibody (Cat. No. 564268; Right Panel). Two-color flow cytometric contour plots showing the correlated expression of Blimp-1 (or Ig Isotype control staining) versus CD45R/B220 were derived from gated events with the forward and side light-scatter characteristics of intact activated splenocytes. Unstimulated splenocytes show a staining pattern similar to Ig Isotype stained cells (data not shown). Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Product Details

Brand: BD Pharmingen™

Alternative Name: Prdm1; PR domain zinc finger protein 1; Blimp1; PRDI-BF1; ZNFPR1A1

Reactivity: Mouse (QC Testing)

Isotype: Rat IgG2a, κ

Immunogen: Mouse Blimp-1 Recombinant Protein

Application: Intracellular staining (flow cytometry) (Routinely Tested)

Concentration: 0.2 mg/ml

RRID: AB_2738718

Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.

Regulatory Status: RUO

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 R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Product Notices

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.

Antibody Details

5E7

The 5E7 monoclonal antibody specifically binds to mouse B lymphocyte-induced maturation protein 1 (Blimp-1). Blimp-1 is a 98 kDa zinc finger-containing protein that is encoded by the Prdm1 gene and functions as a transcriptional repressor. Blimp-1 is essential for regulating the terminal differentiation of activated B cells into plasma cells. In this process, Blimp-1 suppresses genes involved in B cell proliferation, such as Myc and Bcl6. It controls other genes, such as Xbp1, that are required for upregulating the plasma cell's protein synthesis machinery which is essential for antibody production and secretion. Blimp-1 is an important regulator in other cell types as well. It functions in the regulation of T cell activation and homeostasis and NK cell maturation. Blimp-1 is expressed in activated T cells and can function to inhibit IL-2 production while enhancing the differentiation and expression of several molecules produced by effector T cells.

Format Details

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: PE

Excitation Source: Yellow-Green 488 nm, 532 nm, 561 nm
