Background
Cytokeratin 7 is the intermediate silk protein mainly expressed in epithelial cells. The heterodine of keratin consists of a polymerization filament by an acid -keratin (or type I keratin, keratin 9 to 23) and alkaline keratin (or type II keratin, keratin 1 to 8). Expression similar to but more limited than keratins 8 and 18 in simple, pseudostratified and ductal epithelium, mesothelium and urothelium. It's generally expressed (with some variation) in adenocarcinoma of lung, breast, thyroid, endometrium, cervix, ovary, salivary gland, upper GI tract, urothelial carcinoma, papillary renal cell carcinoma and Paget disease. It's generally negative (with some variation) in colorectal carcinoma, Merkel cell carcinoma, hepatocellular carcinoma, prostatic adenocarcinoma, adrenocortical tumors and squamous cell carcinoma.

FC
Flow cytometric analysis of MCF7 (left) / HeLa (right) cells labelling Cytokeratin-7 antibody at 1/500 (0.1ug) dilution/ (red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti-Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody. Negative control: MCF7
IP
Cytokeratin 7 Rabbit mAb at 1/25 dilution (1µg) immunoprecipitating Cytokeratin 7 in 0.4mg T-47D whole cell lysate.
Western blot was performed on the immunoprecipitate using Cytokeratin 7 Rabbit mAb at 1/1000 dilution.
Secondary antibody (HRP) for IP was used at 1/400 dilution.
