Western blot analysis of extracts from HeLa and MCF7 cells using Keratin 7 (D1E4) XP® Rabbit mAb #4465. Note that MCF7 cells are negative for Keratin 7, as expected.
Western blot analysis of extracts from A-431, HeLa, and A549 cells using Keratin 17 (D73C7) XP® Rabbit mAb #4543. As expected, keratin 17 is absent in A549 cells.
Western blot analysis of extracts from various cell lines using Pan-Keratin (C11) Mouse mAb #4545.
Western blot analysis of extracts from various cell lines using Keratin 8/18 (C51) Mouse mAb #4546.
Western blot analysis of extracts from HeLa and A-431 cells using Keratin 18 (DC10) Mouse mAb #4548.
Western blot analysis of extracts from various cell types using Keratin 19 (BA17) Mouse mAb #4558. As expected, the protein is absent in A-431 and HeLa cells.
The Cytokeratin Antibody Sampler Kit provides an economical means to evaluate the presence and status of selected keratin proteins. The kit provides enough primary and secondary antibodies to perform four Western blot experiments per primary antibody.
Specificity / Sensitivity
The pan-keratin (C11) mouse mAb detects endogenous levels of total keratins 4, 5, 6, 8, 10, 13 and 18. The antibody does not cross-react with other keratins. Each of the remaining antibodies included in this kit detect endogenous levels of the specified keratin protein and do not cross-react with other keratin proteins.
Source / Purification
Pan-Keratin Mouse mAb (C11) is produced by immunizing animals with a cytoskeleton preparation from A431 cells. Keratin 8/18 (C51) Mouse mAb is produced by immunizing animals with a cytoskeleton preparation from HeLa cells. Keratin 18 (DC10) Mouse mAb is produced by immunizing animals with human PMC-42 breast carcinoma cells. Keratin 19 (BA17) Mouse mAb is produced by immunizing animals with detergent-insoluble extract of human mammary epithelial organoids. Keratin 7 (D1E4) XP® Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human keratin 7 protein and Keratin 17 (D73C7) XP® Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to amino acids near the carboxy terminus of human keratin 17
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 research 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).
