A1035: Cancer Antigen 72-4 (CA 72-4)

Cancer Antigen 72-4 (CA 72-4) - Gastrointestinal & Gastric Cancer Marker

Cancer Antigen 72-4 (CA 72-4) is a tumor-associated glycoprotein recognized as a key biomarker for gastrointestinal and gastric cancers. This product is derived from cell culture supernatant and manufactured under strict quality controls for high purity and lot-to-lot consistency.

CA 72-4 is widely used in oncology research for monitoring disease progression and validating diagnostic assay performance.
