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. KRT18, also named as CYK18, PIG46 and K18, is the most commonly found members of the intermediate filament gene family. KRT18 is a type I keratin which is found primarily in non squamous epithelia and is present in a majority of adenocarcinomas and ductal carcinomas but not in squamous cell carcinomas.

MALLIKARJUNA (Verified Customer) (10-14-2025) | GOOD FOR IF
|
Jan (Verified Customer) (11-20-2024) | Photo attached represents IF analysis of fixed A549 cells. Cells were incubated with Cytokeratin 18 polyclonal antibody (10830-1-AP) and FITC-conjugated Goat Anti-Rabbit IgG (H+L) (SA00003-2).
 |
Parmveer (Verified Customer) (12-02-2019) | Works well for both IHC and IF, but does come with a bit of background
