Applications Key:  F=Flow Cytometry
Reactivity Key:  H=Human  R=Rat  Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Specificity / Sensitivity

Pan-Keratin (C11) Mouse mAb (PE Conjugate) 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 a BALB/c mouse with a cytoskeleton preparation from A-431 cells.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of MCF7 cells using Pan Keratin (C11) Mouse mAb (PE Conjugate) (blue) compared to concentration matched Mouse (G3A1) mAb IgG1 Isotype Control (PE Conjugate) #6899 (red).

Description

This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometry 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).
