Tn antigen (clone BRIC111) PE, anti-human

Decription:
Mouse monoclonal antibody to human Tn Antigen PE conjugate. Tn is a cryptantigen. It is defined as the core structure of O- glycans (aGalNAc-0-Ser/Thr) but different antibodies may require a contribution to the antigen structure from sialic acid substitution and/or adjacent polypeptide. The antigen is not expressed on normal haemopoietic cells but becomes exposed as a result of an acquired deficiency of b1,3 D-galactosyl transferase. Exposure of Tn antigen on haemopoietic cells is associated with polyagglutination2 and, in some cases thrombocytopenia and/or leucopenia. Detection of the antigen prior to the onset of leukemia has been reported3,4. The Tn antigen has also been described as a useful marker for some types of cancer cells.

Synonyms: Tn Antigen,Tn protein, Cryptantigen
