Specificity/Sensitivity
Blimp-1/PRDI-BF1 (C14A4) Rabbit mAb (PE Conjugate) detects endogenous levels of total Blimp-1/PRDI-BF1 protein.
Species predicted to react based on 100% sequence homology
Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val90 of human PRDI-BF1 isoform 2.
Description
This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometric analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Blimp-1/PRDI-BF1 (C14A4) Rabbit mAb #9115.
Background
Blimp-1 (B lymphocyte-induced maturation protein) is a nuclear zinc-finger containing transcriptional repressor that is considered a master regulator of terminal B cell development (1). The human homolog, PRDI-BF1, was identified by its ability to bind to the PRDI element on the IFN-β promoter and can inhibit virus-mediated IFN-β production (2). Expression of Blimp-1 is sufficient to drive terminal differentiation of BCL1 lymphoma cells into antibody secreting plasma cells, increasing the expression of the cell surface marker Syndecan-1 (1). In the B cell lineage, Blimp-1 is specifically expressed in antibody-secreting cells including activated B and plasma cells. In addition, Blimp-1 has been found during macrophage differentiation (3) and in a subset of T cells (4,5), suggesting it may play a wider role in homeostasis and differentiation (6). Mechanistically, Blimp-1 is thought to act by recruiting chromatin-modifying enzymes including histone deacetylases (7) and methyltransferases (8,9). Target genes of Blimp-1 transcriptional repression with potential roles in differentiation include c-Myc (10), CIITA (11), Pax5 (12), Spi-B, and Id3 (13).
