Background Information

Pan-keratin, also known as pan-cytokeratin, refers to a group of antibodies that recognize a broad array of keratin proteins. Keratins are a large family of intermediate filament (IF) proteins that provide structural integrity to epithelial cells. These proteins are essential for maintaining cell shape, strength, and resilience . The keratin gene family is divided into two major groups: type I keratins (acidic) and type II keratins (basic), with 27 type I and 26 type II keratin genes in humans. Pan-keratin immunostaining is widely used in pathology and research due to its ability to detect a variety of keratin proteins, making it a valuable tool for identifying epithelial cells and tissues. This staining technique is particularly useful in the diagnosis of tumors, as it can help distinguish between epithelial and non-epithelial neoplasms. This antibody is a pan-keratin antibody.
