Total cell lysates (15µg protein) from A549, A431 and NIH3T3 cells were resolved by 4-20% Tris-glycine gel electrophoresis, transferred to nitrocellulose, and probed with 0.5µg/mL purified anti- Cytokeratin 17 (clone W16131A) antibody, competitor’s antibody used at manufactures recommended concentration (upper) or loading control anti-GAPDH (poly6314) antibody (lower). Proteins were visualized by chemiluminescence detection using a goat anti-rat-IgG secondary antibody conjugated to HRP for anti- Cytokeratin 17 antibody, and a donkey anti-rabbit IgG Antibody conjugated to HRP for competitor’s antibody and anti-GAPDH antibody.

A431 cells were fixed with 4% paraformaldehyde (PFA) for fifteen minutes, permeabilized with 0.5% Triton X-100 for three minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained with 2 µg/ml rat IgG2b isotype control (top left), anti-Cytokeratin 17 (clone W16131A, top right), or competitor’s antibody used at manufactures recommended concentration (bottom left) overnight at 4°C followed by Alexa Fluor® 594 (red) conjugated goat anti-rat IgG for anti- Cytokeratin 17 antibody, Alexa Fluor® 594 (red) conjugated donkey anti-rabbit IgG for competitor’s antibody for one hour at room temperature. Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective. -
IHC staining using purified anti-Cytokeratin 17 (clone W16131A) on formalin-fixed paraffin-embedded human bladder tissue. Following antigen retrieval using 1X Tris-Buffered Saline (final concentration 0.05M) with Tween-20 (Cat. No. 925501), the tissue was incubated with (B) or without (A) 10 μg/mL of antibody overnight at 4°C, followed by incubation with 2.5 μg/mL of Alexa Fluor® 647 goat anti-rat IgG (Cat. No. 405416) for one hour at room temperature. Nuclei were counterstained with DAPI (blue) (Cat. No. 422801), and the slide was mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 10X objective. Scalebar = 50 μM -

Cytokeratin 17 (CK-17), also known as KRT17 or keratin-17 (K-17), is a type I intermediate filament protein. KRT expression is normally restricted to ectoderm-derived epithelial appendages such as thymus, glands, skin, hair, tooth, nail, and the endocervical mucosa. Cytokeratin-17 participates in promoting protein synthesis and cell growth through recruiting stratifin (SFN) to the cytoplasm and stimulating the Akt/mTOR pathway. Cytokeratin-17 was found to regulate chemokine expression, including the CXCR3 ligands CXCL9, CXCL10, and CXCL11. Cytokeratin 17 expression can be upregulated in response to chemical stimulation, wounding, and UV irradiation. Increased expression of Cytokeratin 17 is associated with lesion progression and poor prognosis in epithelial carcinoma. Cytokeratin 17 deficient mice show a delay in wound healing and attenuated tumorigenesis.

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.05 - 0.5 µg per ml. For immunocytochemistry, a concentration range of 0.2 - 2.0 µg per ml is recommended. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration of 10.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
This clone does not cross-react with mouse (in-house tested).
As per the Human Protein Atlas RNA level dataset, A549 cell is expected to have a low level of Cytokeratin 17 expression. - RRID
