Molecular Characterization of a Tissue‐Polypeptide‐Specific‐Antigen Epitope and its Relationship to Human Cytokeratin 18
1 Oct 1996
Abstract excerpt
Tissue-polypeptide-specific antigen (TPS) from the human colon adenocarcinoma cell line WiDr was purified using the monoclonal antibody M3 as a probe. Upon SDS/polyacrylamide gradient gel electrophoresis, several TPS-positive bands were detected (corresponding to 13 kDa, 22 kDa and a doublet at 42 kDa). The 13-kDa moiety was purified about 30,000-fold by a 5-step protocol. The electro-phoretically homogeneous...
