Produktdetails anti-PRDM1 Antikörper

Produktmerkmale: The 6D3 monoclonal antibody specifically binds to mouse B lymphocyte-induced maturation protein 1 (Blimp-1) and crossreacts with human BLIMP-1. Blimp-1 is a 98 kDa zinc finger-containing protein that is encoded by the Prdm1 gene. Blimp-1 was first discovered as a transcriptional repressor of the IFN-β promoter. Blimp-1 is critical for primordial germ cells specification in the early embryo and induction of terminal cell differentiation in multiple somatic cell types. It is largely known as a master regulator of antibody-secreting plasma cells due to its function in the repression of PAX5, CIITA and cMYC genes. Blimp-1 also controls T cell homeostasis and effector differentiation through different mechanisms, including repression of IL-17 producing cells. Blimp-1 also plays roles in the maturation and activity of dendritic cells and natural killer cells. Analyses of Blimp-1 Expression Panel 1. Western blot analysis of Blimp-1 expression in human myeloma cell lines. Lysates from RPMI-8226 (ATCC CLL-155, Lane 1) and U266 (ATCC TIB-196, Lane 2) cells were electrophoresed, blotted and probed with Purified Rat Anti-Blimp-1 antibody (Cat. No. 564703) followed by HRP Goat Anti-Rat Ig (Cat. No. 554017), and ECL detection reagents. The antibody detects Blimp-1 isoforms of 88-92 kDa in both cell lysates and 76-78 kDa) in the U266 cell lysate. Note: an unspecific band (~250 kDa) may be observed upon overexposure of the membranes. Panel 2. Flow cytometric analysis of Blimp-1 expression in a human myeloma cell line. RPMI 8226 cells were fixed and permeabilized with the BD Pharmingen™ Transcription Factor Buffer Set (Cat No. 562574/562725) and stained with either Purified Rat IgG2a, κ (Cat. No. 553927, dashed line histogram) or Purified Rat Anti-Blimp-1 antibody (solid line histogram) followed by staining with PE Goat Anti-Rat Ig (Cat. No. 560767). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells. Flow cytometric analysis was performed using a BD FACSCanto™ II Flow Cytometer System. Panel 3. Immunohistochemical staining of human Blimp-1 in human tonsils. Following antigen retrieval with BD Retrievagen A Buffer (Cat No. 550524), the formalin-fixed paraffin-embedded tonsil sections were stained with either Purified Rat IgG2a κ Isotype Control (Left Image) or Purified Rat Anti-Human Blimp-1 antibody (Right Image). A three-step staining procedure that employs Biotin Goat Anti-Rat Immunoglobulin (Cat. No. 559286), Streptavidin-Horseradish Peroxidase (HRP) (Cat. No.550946), and the DAB Substrate Kit (Cat. No. 550880) was used to develop the primary staining reagents. As shown in the Right Image, the Blimp-1 specific antibody primarily stained the nuclei of some Germinal Center cells. Original magnification: 40x.
