• Target：
• BOB.1

• Gene Name：
• POU2AF1 OBF1

• Protein Name：
• POU domain class 2-associating factor 1 (B-cell-specific coactivator OBF-1) (BOB-1) (OCA-B) (OCT-binding factor 1)

• Human Gene Id：
• 5450

• Human Swiss Prot No：
• Q16633

• Immunogen：
• Synthesized peptide derived from human BOB.1 AA range: 150-256

• Specificity：
• This antibody detects endogenous levels of human BOB.1. Heat-induced epitope retrieval (HIER) Citrate buffer of pH6.0 was highly recommended as antigen repair method in paraffin section

• Formulation：
• Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.

• Source：
• Mouse, Monoclonal/IgG2a, Kappa

• Dilution：
• Ready to use for IHC

• Purification：
• The antibody was affinity-purified from mouse ascites by affinity-chromatography using specific immunogen.

• Storage Stability：
• 2°C to 8°C/1 year

• Background：
• disease:A chromosomal aberration involving POU2AF1/OBF1 may be a cause of a form of B-cell leukemia. Translocation t(3;11)(q27;q23) with BCL6.,function:Transcriptional coactivator that specifically associates with either OCT1 or OCT2. It boosts the OCT1 mediated promoter activity and to a lesser extent, that of OCT2. It has no intrinsic DNA-binding activity. It recognizes the POU domains of OCT1 and OCT2. It is essential for the response of B-cells to antigens and required for the formation of germinal centers.,PTM:Ubiquitinated; mediated by SIAH1 or SIAH2 and leading to its subsequent proteasomal degradation.,similarity:Belongs to the POU2AF1 family.,tissue specificity:B-cell specific.,
