Anti-PIGR antibody [6E5A9]

• 概述

• 产品描述Polymeric immunoglobulin receptor (pIgR) is a transmembrane protein that in humans is encoded by the PIGR gene. It is an Fc receptor which facilitates the transcytosis of the soluble polymeric isoforms of immunoglobulin A , and immune complexes. pIgRs are mainly located on the epithelial lining of mucosal surfaces of the gastrointestinal tract. The composition of the receptor is complex, including 6 immunoglobulin-like domains, a transmembrane region, and an intracellular domain. pIgR expression is under the strong regulation of cytokines, hormones, and pathogenic stimuli. Polymeric immunoglobulin receptor is responsible for transcytosis of soluble dimeric IgAs and immune complexes from the basolateral to the apical mucosal epithelial cell surface. pIgR has a strong specificity to polymeric immunoglobulins and is not responsive to monomeric immunoglobulin. The ligand’s J-chain is responsible for the binding of pIgR to its ligand.

  Fig1: Western blot analysis of PIGR against human PIGR (AA: extra 19-170) recombinant protein. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in PBS for 1 hour at room temperature. The primary antibody ( was used in 5% BSA at room temperature for 2 hours. Goat Anti-Mouse IgG - HRP Secondary Antibody at 1:5,000 dilution was used for 1 hour at room temperature.

  Fig3: Immunohistochemical analysis of paraffin-embedded human ovarian cancer tissue using anti-PIGR antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0) for 20 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibodyfor 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
