Function
Cytokeratins comprise a diverse group of intermediate filament proteins that are expressed as pairs in both keratinized and non-keratinized epithelial tissue. Cytokeratins play a critical role in differentiation and tissue specialization and function to maintain the overall structural integrity of epithelial cells. Cytokeratin 9 is an unusually large, type I acidic cytokeratin that differentiates human plantar and palmar epidermal cells. Cytokeratin 9 localizes to the suprabasal layers as well as the upper epidermal layers such as the glandular ridges and interridges. The domains of cytokeratin 9 include a head, an α-helical coiled-coil-forming rod, and a tail; cytokeratin 9 shares significant homology with cytokeratin 10. Mutations in the cytokeratin 9 gene correlate with the development of epidermolytic palmoplantar keratoderma (EPPK), an autosomal dominant inherited skin disorder that is characterized by hyperkeratosis of the skin over the palms and soles.

Predicted band size: 62 kDa
Observed band size: 62 kDa
Exposure time: 18 seconds; ECL: K1801;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET1612-77) at 1/1,000 dilution was used in primary antibody dilution (K1803) at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. -
Immunohistochemical analysis of paraffin-embedded mouse skin tissue using anti-Cytokeratin 9 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ET1612-77, 1/50) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunofluorescence analysis of paraffin-embedded human breast tissue labeling Cytokeratin 9 (ET1612-77) and Vimentin (EM0401).
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS. And then probed with the primary antibodies Cytokeratin 9 (ET1612-77, red) at 1/50 dilution and Vimentin (EM0401, green) at 1/500 dilution at +4℃ overnight, washed with PBS.
Goat Anti-Rabbit IgG H&L (iFluor™ 594, HA1122) and Goat Anti-Mouse IgG H&L (iFluor™ 488, HA1125) were used as the secondary antibodies at 1/1,000 dilution. Nuclei were counterstained with DAPI (blue). -

Immunocytochemistry analysis of MCF-7 cells labeling Cytokeratin 9 (ET1612-77).
Cells were fixed in 4% paraformaldehyde and permeabilized with 0.05% Triton X-100 in PBS for 10 minutes, and then blocked with 2% negative goat serum for 15 minutes at room temperature. Cells were probed with the primary antibody Cytokeratin 9 (ET1612-77, red) at 1/200 dilution for overnight at 4℃.
Goat Anti-Rabbit IgG H&L (iFluor™ 594, HA1122) was used as the secondary antibody at 1/800 dilution. DAPI was used to stain the cell nuclei (blue).
