Related Product Information for anti-KRT4 antibody
Cytokeratins are a subfamily of intermediate filament keratins that are characterized by a remarkable biochemical diversity, which is represented in human epithelial tissues by at least 20 different polypeptides. Cytokeratins range in isoelectric range between 4.9 and 7.8. Cytokeratin 1 has the highest molecular weight, while Cytokeratin 19 has the lowest molecular weight. The cytokeratins are divided into the type I and type II subgroups. Type II family members comprise the basic to neutral members, Cytokeratins 1-8, while the type I group comprises the acidic members, Cytokeratins 9-20. Various epithelia in the human body usually express cytokeratins which are characteristic of the type of epithelium and related to the degree of maturation or differentiation within said epithelium. Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. Cytokeratin 4 is expressed in differentiated layers of the mucosal and esophageal epithelia along with Cytokeratin 13.

Uniprot Description

K4: Heterotetramer of two type I and two type II keratins. Keratin-4 is generally associated with keratin-13. Detected in the suprabasal layer of the stratified epithelium of the esophagus, exocervix, vagina, mouth and lingual mucosa, and in cells and cell clusters in the mucosa and serous gland ducts of the esophageal submucosa. Expressed widely in the exocervix and esophageal epithelium, with lowest levels detected in the basal cell layer. Belongs to the intermediate filament family.

Product Notes

The Cytokeratin 4 krt4 (Catalog #AAA3012564) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Cytokeratin 4 Polyclonal Antibody reacts with Human, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's Cytokeratin 4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunocytochemistry (ICC), Immunofluorescence (IF), Immunohistochemistry (IHC). WB: 1:1,000-1:2,000 ICC: 1:50-1:200 IHC: 1:50-1:200. Researchers should empirically determine the suitability of the Cytokeratin 4 krt4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Cytokeratin 4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
