Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Pan-Keratin (C11) Mouse mAb (Biotinylated) detects endogenous levels of total keratin 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.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa and H-4-II-E cells using Pan-Keratin (C11) Mouse mAb (Biotinylated) detected using Streptavidin-HRP #3999.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of MCF7 cells using Pan-Keratin (C11) Mouse mAb (Biotinylated) (blue) compared to Mouse (MOPC-21) mAb IgG1 Isotype Control (Biotinylated) #4097 (red).

Description

This Cell Signaling Technology (CST) antibody is conjugated to biotin under optimal conditions. The unconjugated Pan-Keratin (C11) Mouse mAb #4545 reacts with human, rat and monkey pan-keratin. CST expects that Pan-Keratin (C11) Mouse mAb (Biotinylated) will also recognize pan-keratin in these species.

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).
