Source
A mouse was immunized with cytokeratin isolated from a human breast carcinoma cell line (MCF-7). 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 simple epithelia in thin sections.

Specification:
The antibody stains almost all epithelial cells. In immunoblotting experiments the antibody was shown to recognize cytokeratin no. 8 (52 kDa).
