Collagen IV, technical component
Use
Collagen IV is a major component of the basement membrane, providing structural support to tissues and playing a role in cellular signaling. In pathology, collagen IV is used to assess the integrity and function of basement membranes, particularly in kidney and lung diseases, as well as in the diagnosis of tumors, such as renal cell carcinoma and various metastatic cancers. Technical component only. Pathologist read not included.
