Bovine Polymeric Immunoglobulin Receptor (PIGR) ELISA Kit

The Polymeric Immunoglobulin Receptor (PIGR) is a transmembrane protein responsible for transcytosis of polymeric IgA and IgM across mucosal epithelial barriers. In cattle, PIGR is central to passive immunity transfer via colostrum and supports mucosal defense in the gastrointestinal tract, mammary gland, and respiratory system. Researchers use this kit to quantify PIGR in serum and tissue homogenates for studies spanning neonatal calf immunology, mastitis, bovine respiratory disease, and gut barrier integrity. The plate-based microplate format includes pre-coated capture wells, detection antibody, lyophilized standards, and substrate reagents sufficient for 100 uL sample volumes. Components should be refrigerated upon arrival; reconstituted reagents remain stable for short-term use when kept cool and protected from light. Each Assay Genie kit supports quantitative measurement using a standard curve approach, with results suitable for downstream correlation with immunoglobulin transport studies, mucosal inflammation markers, and vaccine response trials in bovine research.
