Background

A group of 19 different water-insoluble proteins forms the cytokeratins. Together with microtubules and microfilaments, they form the cytoskeleton of epithelial cells. Normally, it is the case that different cytokeratins are found simultaneously in one cell. This is independent of cell type, cell environment, disease and differentiation stage.

If a conversion from normal to neoplastic cells takes place, the expression of these proteins is maintained.

Specificity

Keratins are a group of water-insoluble proteins that form monofilaments, a´class of intermediate filament. These filaments form part of the cytoskeletal complex in epidermis and in most other epithelial tissues. Nineteen human epithelial keratins are resolved with two-dimensional gels electrophoresis (1). These can be divided into acid (pI <5.7) and basic (pI >6.0) subfamilies. Anti-Keratin AE1 recognizes the 56.5, 50, 50’, 48, and 40 kD keratins of the acidic subfamily. Anti-Keratin AE3 recognizes all members of the basic subfamily. Anti-Keratin AE1 And AE3 monoclonal antibodies have been used to characterize the source of various neoplasms and to study the distribution of keratin-containing cells in epithelia during normal development and during the development of epithelial neoplasms (8-13).

Fusion Partners

Spleen cells from an immunised BALB/c mouse were fused with cells of the mouse P3 myeloma cell line

Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.

Immunohistology

Pre-treatment

Proteolytic (0.1% Pronase LINARIS CatNo E110) treatment enhances specific staining of formalin-fixed
paraffin-embedded tissue sections and allows higher dilutions of the antibody to be used (14).
