    • IHC image of CSB-RA280291A0HU diluted at 1:100 and staining in paraffin-embedded human tonsil tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

  • 产品描述：

    POU2AF1 is a gene that was previously thought to be expressed only in lymphocytes, where it regulates immunoglobin production and other host defense-related genes as a co-activator of octamer-binding transcription factors OCT1 and OCT2. POU2AF1 has no intrinsic DNA binding activity but can recognize the POU domain of OCT1 and OCT2. It plays an essential role in B-cell responses to antigens and is required for the formation of germinal centers. In addition to modulating the IgG gene in B cells, POU2AF1 contains numerous known downstream genes with various functions in lymphocytes, including cellular metabolism, cell survival, surface receptors, ion transport, and cell adhesion.

    CUSABIO cloned POU2AF1 antibody-coding genes into plasma vectors and then transfected these vector clones into mammalian cells using a lipid-based transfection reagent. Following transient expression, the recombinant antibodies against POU2AF1 were harvested and characterized. The recombinant POU2AF1 antibody was purified by Affinity-chromatography from the culture medium. It can be used to detect POU2AF1 protein from Human in the ELISA, WB, IHC.

  • 功能：
    Transcriptional coactivator that specifically associates with either POU2F1/OCT1 or POU2F2/OCT2. It boosts the POU2F1/OCT1 mediated promoter activity and to a lesser extent, that of POU2F2/OCT2. It has no intrinsic DNA-binding activity. It recognizes the POU domains of POU2F1/OCT1 and POU2F2/OCT2. It is essential for the response of B-cells to antigens and required for the formation of germinal centers. Regulates IL6 expression in B cells as POU2F2/OCT2 coactivator.
