Protocols

Specificity / Sensitivity

Pan-Keratin (C11) Mouse mAb (Alexa Fluor® 555 Conjugate) detects endogenous levels of total keratins 4, 5, 6, 8, 10, 13 and 18. The antibody does not cross-react with other keratins.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a cytoskeleton preparation from A-431 cells.

Confocal immunofluorescent analysis of MCF7 cells using Pan-Keratin (C11) Mouse mAb (Alexa Fluor® 555 Conjugate) (red). Blue pseudocolor = DRAQ5® #4084 (fluoresent DNA dye).

Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 555 fluorescent dye and tested in-house for immunofluroescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated Pan-Keratin (C11) Mouse mAb #4545.

Background

Keratins (cytokeratins) are intermediate filament proteins that are mainly expressed in epithelial cells. Keratin heterodimers composed of an acidic keratin (or type I keratin, keratins 9 to 23) and a basic keratin (or type II keratin, keratins 1 to 8) assemble to form filaments (1,2). Keratin isoforms demonstrate tissue- and differentiation-specific profiles that make them useful as biomarkers (1). Research studies have shown that mutations in keratin genes are associated with skin disorders, liver and pancreatic diseases, and inflammatory intestinal diseases (3-6).
