PIGR

Alternative Names: Polymeric immunoglobulin receptor, PIGR, PIgR, Poly-Ig receptor, Hepatocellular carcinoma-associated protein TB6, polymeric immunoglobulin receptor precursor.

The PIGR protein facilitates the movement of soluble dimeric IgA and immune complexes through epithelial cells. Specifically, PIGR binds to polymeric IgA and IgM at the basolateral surface of the cells, and then transports the complex across the cell so that it can be secreted at the apical surface. The expression of PIGR is regulated by various factors including pro-inflammatory cytokines such as IL-1, IL-4, TNF-alpha, and IFN-gamma.

Product Description

The Recombinant Human Polymeric Immunoglobulin Receptor (pIgR) is a protein that plays a critical role in the transportation of immunoglobulins across mucosal surfaces. Belonging to the immunoglobulin superfamily, pIgR is a transmembrane glycoprotein with a molecular weight of approximately 80-90 kDa. This receptor is primarily expressed in epithelial cells of mucosal tissues such as the respiratory, gastrointestinal, and urogenital tracts. By binding to immunoglobulins, pIgR facilitates their transport from the basolateral to the apical side of epithelial cells, enabling their secretion into mucosal secretions. This mechanism is vital for the protection of mucosal surfaces against pathogens and contributes to the maintenance of immune homeostasis.

Storage Instruction

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

Sample Prep Instruction

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
