Cytokeratin Type II (Biotin)
Description:
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.

Applications:
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.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
