|Produced in rabbits immunized with purified, recombinant Human PIGR extracellular domain (rh PIGR; Catalog#10131-H08H; NP_002635.2; Met 1-Arg 638). Total IgG was purified by Protein A affinity chromatography.|
ELISA: 0.5-1.0 μg/mL
This antibody can be used at 0.5-1.0 μg/mL with the appropriate secondary reagents to detect Human PIGR. The detection limit for Human PIGR is 0.00245 ng/well.
Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
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.
