Specificity / Sensitivity

BACH2 Antibody recognizes endogenous levels of total BACH2 protein.


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala304 of human BACH2 protein. Antibodies are purified by protein A and peptide affinity chromatography.

The transcription regulator BTB and CNC homolog 2 (BACH2) is a bZIP domain-containing transcriptional repressor that dimerizes with MafK and binds Maf recognition elements (MAREs) to regulate transcription (1,2). BACH2 is part of a network of transcription factors that controls the transition of activated B cells into either antibody-producing plasma cells or memory B cells (3-5). Plasma cell differentiation requires the transcription factor Blimp1 (6). BACH2 suppresses expression of Blimp1 in activated B cells, which delays plasma cell differentiation and allows time for class switch recombination and somatic hypermutation (3-5). Genome-wide association studies have linked the genetic locus containing BACH2 to several immune-related disorders including type 1 diabetes, celiac disease, Crohn’s disease, and the skin condition known as vitiligo (7-10).
