Abstract
Sensitive and specific monoclonal antibodies (mAbs) targeting podoplanin (PDPN) are needed for immunohistochemical analyses as a marker for lymphatic endothelial cells. We recently have developed anti-PDPN mAbs against many species, including human, mouse, rat, rabbit, dog, cat, bovine, pig, Tasmanian devil, alpaca, tiger, whale, goat, horse, and bear. However, anti-sheep PDPN (sPDPN) has not yet been established. In this study, we used the Cell-Based Immunization and Screening method for the development of anti-sPDPN mAbs. RAP14 tag was added to N-terminus of sPDPN, and anti-RAP14 tag mAb (PMab-2) was used to detect the expression level of sPDPN in flow cytometry and western blot. We immunized mice with sPDPN-overexpressing Chinese hamster ovary (CHO)-K1 (CHO/sPDPN) cells and screened mAbs against sPDPN using flow cytometry. One of the mAbs, PMab-256 (IgG1, kappa), specifically detected CHO/sPDPN cells by flow cytometry and western blot. Furthermore, PMab-256 stained type I alveolar cells of lung, renal glomerulus and Bowman's capsule, and lymphatic endothelial cells of lung and colon. Our findings suggest the potential usefulness of PMab-256 for the functional analyses of sPDPN.
