Podoplanin (PDPN, M2A Antigen) (D2-40)

Catalogue number: PDP001-0.5

Units0.5 ml
Application IHC (C

This antibody is well suited for the detection of podoplanin in histological sections and cells. Podoplanin is a highly glycosylated glycoprotein (162 AS, 36 kDa) that is predominantly expressed on lymphatic endothelia. Therefore antibodies against podoplanin are often used as a marker for lymphatic vessels. Podoplanin is a protein that is also found on podocytes of the kidney glomeruli (therefore the name podoplanin) and in fetal testis. Since a while podoplanin is considered as a good marker for the malign pleuramesothelioma and is used for differential diagnosis of this disease (Ordonèz, 2005). Normally podoplanin occurs in lymphatic vessels, placenta, lung, and skeletal muscles. Appearance in testicular germ cells, lymphangioma and lymphangiosarcoma is noticeable. In haemangioma und other diseases of the vessels overexpression of the glycoprotein is not found. Podoplanin, M2A Antigen of lymphatic endothelia.


Immunogen: M2A Antigen, Podoplanin

Affinity purified antibody in PBS, BSA, NaN3

Purification Method: Affinity purified antibody in PBS, BSA, NaN3

Secondary Reagents: Anti-mouse IgG:Biotin conjugate (code no. ZU102) in combination with Streptavidin-HRPO (code no. ZU054) and a suitable substrate e.g. DAB (Ref. DA002) or AEC (Ref AE002).


Species Reactivity: Human, other species not tested


Working Concentration: (liquid conc.) 1:30-1:100

Pre-Treatment: The best pre-treatment of paraffin sections has not been validated at our lab. Meanwhile we suggest the usage of routine heat induced antigen retrieval although some laboratory results were positive without any unmasking.

Positive Control: Lymph nodes, Germ cell tumors


These antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals. The preservative sodium azide has been added in very small quantities. Nevertheless, it may be harmful to health and the reagent should be used only by trained personnel. For waste disposal, please refer to national regulations.
