BLIMP1 / PRDM1 (Beta-interferon gene positive regulatory domain I-binding factor, PR domain-containing protein 1 Positive regulatory domain I-binding factor 1) is a DNA sequence-specific transcriptional repressor that binds specifically to the PRDI element in the promoter of the beta-interferon gene, as well as other genes. It is required for maturation of B-lymphocytes into immunoglobin secreting plasma cells through direct repression of transcription factors such as Pax5, Bcl6, and Myc, which function in the lineage commitment and proliferation of B cells. BLIMP1 / PRDM1 contains an N-terminal SET domain and four C-terminal C2H2-type zinc-finger motifs. It is also required for effector T-cell function and for the specification of primordial germ cell lineages.

Positive Control

Active Motif's Saos-2 nuclear extract (Catalog No. 36025) can be used as a positive control for BLIMP1 / PRDM1 antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
