Species Reactivity
Detects mouse pIgR in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 5% cross-reactivity with recombinant human pIgR is observed.
Polyclonal Goat IgG
Antigen Affinity-purified
Mouse myeloma cell line NS0-derived recombinant mouse pIgR
Accession # O70570
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Blockade of Receptor-ligand Interaction
In a functional ELISA, 0.5-2.5 µg/mL of this antibody will block 50% of the binding of 5 μg/mL of mouse IgM to immobilized Recombinant Mouse pIgR (Catalog # 2800-PG) coated at 5 µg/mL (100 µL/well). At 50 μg/mL, this antibody will block >90% of the binding.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Scientific Data

Western Blot Detection of Mouse pIgR antibody by Western Blot. View Larger

Detection of Mouse pIgR by Western Blot. Western blot shows lysates of mouse liver tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Mouse pIgR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2800) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). Specific bands were detected for pIgR at approximately 85 to 115 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

pIgR in Mouse Liver. pIgR was detected in immersion fixed frozen sections of mouse liver using Goat Anti-Mouse pIgR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2800) at 1 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to hepatocyte cytoplasm and plasma membrane. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: pIgR

The mouse polymeric immunoglobulin receptor (plgR; also known as membrane secretory component) is a 115 kDa type I transmembrane glycoprotein that is synthesized as a 771 amino acid (aa) precursor. It includes an 18 aa signal sequence, a 627 aa extracellular domain (ECD) (aa 19‑645), a 23 aa transmembrane segment (aa 646‑668), and a 143 aa cytoplasmic region (aa 669‑771) (1‑3). The ECD consists of five V-type Ig-like domains and a sixth non-Ig domain that connects to the transmembrane region. The ECD of mouse plgR is 65%, 69%, 85%, 62% and 62% aa identical to the equivalent region in human, porcine, rat, bovine and canine, respectively. plgR is expressed on secretory epithelial cells and serves as a carrier that transports IgA and IgM across epithelium (1, 2, 4). On the basolateral surface of epithelial cells, the receptor initially binds non-covalently to IgA via domains #1 and #5 of the plgR. A rearrangement then occurs where a disulfide bond forms between domain #5 of the plgR and an IgA heavy chain (2). This complex is then internalized and transcytosed to the apical surface. A soluble covalent complex called secretory IgA (SIgA) is generated by proteolytic cleavage of the complex in the sixth extracellular domain of plgR and released into the lumen (5). This proteolytically generated plgR fragment is referred to as secretory component (SC). Notably, in human, plgR transcytoses constitutively, with or without ligand, creating both a bound and free, 78 kDa SC following cleavage (3). In mouse, this event would be expected to generate a 95 kDa fragment (1). The receptor component of the complex anchors the SIgA molecule to mucous (6), where it serves to protect mucous membranes that form a barrier between the interior of the body and the external environment (7).
