Technical Data
Cytokeratin Type II (Biotin)
Cytokeratin Type II constitutes the Type II intermediate filaments (IFs) of the intracytoplasmatic cytoskeleton, which is present in all mammalian epithelial cells. The type 2 cytokeratins consist of basic or neutral, high molecular weight proteins which are arranged in pairs of heterotypic Type I and Type II keratin chains in vivo, coexpressed during differentiation of simple and stratified epithelial tissues.

Suitable for use in Flow Cytometry, ELISA, Western Blot, Cell sorting and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry (frozen tissue and cytological material): 10-20ug/ml; dilute with PBS, pH 7.4; Incubation Time: 1 hr at RT.
Optimal dilutions to be determined by the researcher.

Biotin Coupling Ratio:
5mol Biotin/1mol IgG.
