Background Information
Keratins are a large family of proteins that form the intermediate filament cytoskeleton of epithelial cells, which are classified into two major sequence types. Type I keratins are a group of acidic intermediate filament proteins, including K9-K23, and the hair keratins Ha1-Ha8. Type II keratins are the basic or neutral courterparts to the acidic type I keratins, including K1-K8, and the hair keratins, Hb1-Hb6. Keratin 17 is a type I cytokeratin. It is found in nail beds, hair follicles, sebaceous glands, and other epidermal appendages. It is used as a marker for trauma. This antibody is specifically against KRT17.

Reviews
What customers say
One reviewer (Lindsey Rhea, Aug 2025) gave this antibody a 5-star rating for immunofluorescence on mouse skin. They reported excellent performance on both FFPE tissue (using heat-based citrate buffer antigen retrieval) and whole mount embryonic skin. The antibody showed high specificity and worked well at dilutions of 1/1000 for adult tissue and 1/1200 for embryonic samples. Overall, the reviewer was very satisfied with the product's performance and specificity.

Lindsey (Verified Customer) (08-08-2025) | This antibody works very well on both FFPE tissue (with heat based citrate buffer antigen retrieval) and whole mount embryonic skin. It is highly specific based on our experience and can be used from 1/1000 to 1/1200 dilution (1/1000 for adult and 1/1200 for embryonic).
