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%.
Biohazard
Tested at the serum donor level by FDA approved methods and found negative for HIV1 & 2 antibodies and antigen, HCV antibodies and HBsAg.
Preparation and Storage
Store at 4°C for short term, -20°C for longer storage.

Product Notes
The CA 19-9 (Catalog #AAA537105) is a Native Protein and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's CA 19-9 can be used in a range of immunoassay formats including, but not limited to, Excellent for controls and calibrators. This product is usually used to make standards, calibrators and single analyte controls, and for multiple tumor marker analyte controls due to the highly reproducible low cross reactivity of all major tumor marker antigens especially Ca125 and Ca 15-3. Researchers should empirically determine the suitability of the CA 19-9 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CA 19-9, Native Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
