Description			Gastrointestinal tumor antigen is a large glycoprotein defined by a carbohydrate epitope, CA 19-9, 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%. Source: CA 19-9, from human colon adenocarcinoma cell line. Applications: Suitable for use for making standards, calibrators, and single analyte controls. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
