Human Carbohydrate Antigen 50 ELISA Kit

The Carbohydrate Antigen 50 (CA 50) target is a sialylated glycoprotein tumor marker recognized by the monoclonal antibody clone C-50. Elevated serum CA 50 levels are clinically associated with pancreatic adenocarcinoma, colorectal carcinoma, gastric cancer, and hepatocellular carcinoma, making this Antibodies.com assay particularly valuable for oncology research workflows and longitudinal patient monitoring studies. The quantitative two-antibody immunoassay design supports measurement of CA 50 in human serum samples with a recommended 50 µL sample volume per determination, accommodating studies in cancer biomarker discovery, gastrointestinal malignancy screening investigations, and postsurgical recurrence surveillance. Reconstituted reagents should be refrigerated and protected from light to preserve antibody binding activity across the 96-test microplate format.
