  • Function
    Transcriptional repressor that binds specifically to the PRDI element in the promoter of the beta-interferon gene (PubMed:1851123). Drives the maturation of B-lymphocytes into Ig secreting cells (PubMed:12626569).
  • Sequence similarities
    Belongs to the class V-like SAM-binding methyltransferase superfamily.
    Contains 4 C2H2-type zinc fingers.
    Contains 1 SET domain.
  • Post-translational
    Sumoylation at Lys-816 by PIAS1 augments transcriptional repressor activity, and is critical for plasma cell differentiation.
    Ubiquitinated by the SCF(FBXO11) complex, leading to its degradation by the proteasome.

  • Ab13700 staining (1µg/ml) of human Lymph Node lysate (RIPA buffer, 35µg total protein per lane).  Primary incubated for 1 hour.  Detected by western blot using chemiluminescence.

  • Anti-PRDM1/Blimp1 antibody - ChIP Grade (ab13700) at 1 µg/ml (for 1 hour) + Human brain (cerebellum) lysate in RIPA buffer at 35 µg

    Predicted band size: 91 kDa

  • Human RPMI8226 cells stained with ab13700 at 5 µg/ml, incubated for 30 minutes at 4°C.  In parallel, cells were stained with goat IgG at an equivalent concentration to that of PRDM1. The secondary antibody was a FITC-conjugated rabbit anti-goat IgG F(ab)2.  PRDMI expression was analysed by flow cytometry.

RPMI8226 cell line
Cell harvesting/tissue preparation method: The cells were harvested and stained with 7AAD for 20 minutes on ice in the dark before the cells were fixed and permeabilised using the BD Cytofix/Cytoperm kit. Intracellular staining for PRDM1 was performed in Perm/wash in the presence of 10% human AB serum for 30 minutes on ice in the dark. In parallel, cells were stained with goat IgG at an equivalent concentration to that of PRDM1. Following three washes in Perm/wash the cells were stained with FITC-conjugated rabbit anti-goat IgG for 30 min on ice in the dark. Following three washes PRDMI expression was analysed by flow cytometry.
Sample buffer: BD Cytofix/Cytoperm
Yes - BD Cytofix/Cytoperm Kit
Gating Strategy
All live RPMI8226 cells were included in the analysis. Dead cells were excluded in FL-3 using 7AAD.
