Human epidermal keratinocytes express under various growth conditions a total of at least nine keratins that can be divided into two subfamilies. Subfamily A comprises 40-, 46-, 48-, 50-/50'-, and 56.5-kilodalton (kd) keratins which are relatively acidic (pI less than

Intermediate filaments (IFs) of the cytokeratin (CK) type are cytoskeletal elements typical for epithelial differentiation. However, in diverse transformed culture lines of non-epithelial origin, rare cells emerge spontaneously, which synthesize, in addition to their vimentin IFs, CKs 8 and 18.

The American journal of surgical pathology, 12 Suppl 1, 24-42 (1988-01-01)
The past few years have seen great progress in our knowledge of the biology and the chemistry of intermediate filaments and other filamentous proteins. This has translated into the development of antibodies that, together with new, highly sensitive immunohistochemical methods
A M Gown et al.

A panel of monoclonal antibodies to human intermediate filament proteins was tested on an unselected series of 246 neoplasms. The antibody panel includes two different anti-cytokeratin antibodies, an anti-vimentin antibody, and an anti-neurofilament antibody (Gown and Vogel, Am J Pathol

The Journal of investigative dermatology, 81(1 Suppl), 109s-115s (1983-07-01)
Keratins are a group of water-insoluble proteins (molecular weight range 40-70 K) that form 10-nm tonofilaments in a wide variety of epithelial cells. The subunit composition of the keratin filaments varies with cell type, period of embryonic development, stage of
