ARA Antibodies for Research Applications

Anti-human cytokeratin no. 13 (clone 1C7)

           "Binding of 1C7 monoclonal antibodies to human cytokeratin no. 13"

Hybridoma Clone    Antibody Isotype    Cat. No.
Clone 1C7                Mouse IgG2a         ARA23

A mouse was immunized with cytokeratin purified from human esophagus. Antibody producing cells were isolated after fusing the spleen cells of this mouse with murine myeloma cells by selecting the cells that produced antibodies capable of staining human epithelia in thin sections.

The antibody does not stain non-cornified squamous epithelia, except cornea and transitional epithelial regions, with the exception of basal cell layers of some stratified epithelia (ref. 1). In immunoblotting experiments the antibody was shown to recognize only cytokeratin no. 13 (54 kDa).
