Recombinant monoclonal antibody to RAP tag. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma PMab-2.
UniProt Accession Number of Target Protein: Q64294
Alternative Name(s) of Target: Podoplanin; E11 antigen epitope; Glycoprotein 38; Gp38; OTS-8; Ots8; RTI140; T1-alpha; T1A; Type I cell 40 kDa protein
Immunogen: This antibody was raised by immunising mice with 14-residue synthetic peptide rpp3851, which corresponds to amino acids 38-51 (GDDMVNPGLEDRIEC) of the platelet-aggregation-stimulating (PLAG) domain of rat podoplanin (PDPN). Spleen cells were then harvested, and fused to P3U1 cells to generate stable hybridomas.
Specificity: This antibody is specific for amino acids 38-51 (GDDMVNPGLEDRIEC) of the platelet-aggregation-stimulating (PLAG) domain of rat podoplanin (PDPN). PDPN is a is a type I transmembrane protein that interacts with the platelet receptor C-type lectin-like receptor-2 (CLEC-2). PDPN is expressed by a wide variety of cells, including podocytes, lymphatic endothelial cells and type I alveolar cells. PDPN is also upregulated on certain cancer cells, where it mediates tumour-induced platelet aggregation by binding to CLEC-2 on platelets
Application Notes: The specificity of this antibody for endogenous rat podoplanin (PDPN) has been confirmed in ELISA, Western blot and flow cytometry analysis (Oki et al, 2015), where PMab-2 was shown not to react with human and mouse podoplanin. Flow cytometry has also been used to demonstrate the high binding affinity of this antibody (KD of PMab-2 = 5.9 × 10−10 M) (Oki et al, 2015). In immunohistochemical analysis, this antibody is highly sensitive to rat PDPN, detecting type I lung alveolar cells, colon lymphatic endothelial cells, podocytes and Bowman's capsule epithelial cells at low concentration (Oki et al, 2015). This antibody possess high affinity and specificity for the RAP epitope tag (DMVNPGLEDRIE), and can, therefore, be used to detect proteins in Western blots, flow cytometry and sandwich enzyme-linked immunosorbent assays (ELISA), as well as for protein purification.
