Podoplanin (PDPN), a type I transmembrane glycoprotein, is expressed in several body tissues, including podocytes of renal glomerulus, type I alveolar cells of lung, and lymphatic endothelial cells. PDPN activates platelet aggregation by binding to C-type lectin-like receptor-2 (CLEC-2) presented on platelets. Monoclonal antibodies (mAbs) against human-, mouse-, rat-, rabbit-, dog-, bovine-, and cat-PDPN have already been established. However, anti-horse PDPN mAbs have not yet been developed. In this study, we immunized mice with synthetic horse PDPN peptides and developed anti-horse PDPN mAbs. One of the established mAbs, PMab-202 (IgG1, kappa), was specifically able to detect horse PDPN in Chinese hamster ovary/horse PDPN (CHO/horPDPN) cells in flow cytometry experiments. PMab-202 was also able to detect endogenous horse PDPN expressed in and a horse kidney cell line, FHK-Tcl3.1, in flow cytometry and Western blot analyses. PMab-202 is expected to prove useful in investigating the function of horse PDPN.

01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:25Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
