Related Product Information for CA 19-9 native protein
Description: Purified CA 19-9 protein
Biological Significance: Gastrointestinal tumor antigen is a large glycoprotein defined by a carbohydrate epitope, Ca19-9, located on a protein core mucin. It is referred to in the literature as sialylated Lewis A (Lea). It is over expressed by epithelial tumors of the gastro intestine including the stomach, small and large intestine, colon, pancreas and cervix. These mucins are largely carbohydrate, 80-90%.
