PIGR Matched ELISA Antibody Pair Set,Mouse
Solid Phase Sandwich ELISA
Quantitative determination of Mouse PIGR
1. Capture Antibody 1.0 mg/mL of rabbit anti-mouse PIGR monoclonal antibody, Dilute to a working concentration of 2.0 μg/mL in CBS before coating. (Catalog: # 50119-R040)
2. Detection Antibody 0.5 mg/mL rabbit anti-mouse PIGR polyclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use.
3. Standard Each vial contains 50 ng of recombinant mouse PIGR. Reconstitute standard powder with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 500 pg/mL is recommended.

Polymeric immunoglobulin receptor, also known as PIGR, is a member of the immunoglobulin superfamily and a Fc receptor. The ectodomain of this receptor consists of five units with homology to the variable units of immunoglobulins and a transmembrane region, which also has some homology to certain immunoglobulin variable regions. PIGR is expressed on several glandular epithelia including those of liver and breast. The deduced amino-acid sequence has a length of 764 residues and shows an overall similarity of 56% and 64% with the rabbit and rat counterpart. PIGR mediates transcellular transport of polymeric immunoglobulin molecules, and thus facilitates the secretion of IgA and IgM. During this process, a cleavage occurs that separates the extracellular (known as the secretory component) from the transmembrane segment of PIGR.
