Scientific Data

Intracellular Staining by Flow Cytometry

Detection of BLIMP1/PRDM1 in Human PBMCs by Flow Cytometry. Human peripheral blood mononuclear cells (PBMCs) gated on CD19+CD3-cells were stained with Mouse Anti-Human BLIMP1/PRDM1 PE-conjugated Monoclonal Antibody (Catalog # IC36081P) and Mouse Anti-Human CD38 PerCP-conjugated Monoclonal Antibody (Catalog # FAB2404C). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Product Background

Human BLIMP1 (B lymphocyte-induced maturation protein 1, also known as PRDM1) is a 91 kDa zinc-finger transcriptional repressor that promotes B cell maturation into plasma cells. It is 789 amino acids (aa) in length, and contains an N-terminal S-E-T domain (aa 64-170) and four C-terminal C2H2-type zinc-finger motifs (aa 539‑645). The SET domain interacts with chromatin modifers, while the zinc fingers bind to DNA. There is one 80 kDa, 691 aa alternate splice form that utilizes an intenal start site. This results in a substitution of three aa for the first 101 aa of the long form, and the loss of the SET domain. At least 10 mutations exist, resulting in proteins of 61‑603 aa in length. Over aa 667-789, human BLIMP1 is 89% aa identical to mouse BLIMP1.
