Also for PRDM1 (NM_001198)
|This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a region near the C-terminus of human, mouse, and rat PRDM1/BLIMP1.|
|human, mouse, rat, dog
||ELISA: 1:65,000 - 1:80,000, WB: 1:1,000, IP: 5-10 ug/mL
|0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2|
|PRDM1/Blimp1 (PR domain zinc finger protein 1, PR domain-containing protein 1, Beta-interferon gene positive regulatory domain I-binding factor, BLIMP-1, Positive regulatory domain I-binding factor 1, PRDI-binding factor 1, or PRDI-BF1, or Beta-lymphocyte-induced maturation protein 1) is one of several transcription factors which drives the maturation of B-lymphocytes into Ig secreting cells. In the nucleus, PRDM1/BLIMP1 functions as a transcriptional repressor that binds specifically to the PRDI element in the promoter of the beta-interferon gene. Transcription of the PRDM1 gene is increased upon virus induction. PRDM1/Blimp1 also interacts with PRMT5. Two alternatively spliced transcript variants that encode different isoforms have been reported.

WB using Anti-PRDM1/BLIMP1 antibody show detection of overexpressed PRDM1/BLIMP1 in whole transfected Raji cell lysate (lane 2) at ~88kDa. Lane 1 shows mock transfection in whole Raji cell lysate. Detection of endogenous PRDM1/BLIMP1 (lane 4) is illustrated in human plasma cell nuclear extract, but not in Raji whole cell nuclear extract (lane 3). The identity of the lower dark band at ~50-60kDa is unknown. Primary antibody was used at a 1:1000 dilution in 5% PBS-Tween.
