Technical Data
C0075-31
CA19-9 Cancer Antigen (Pancreatic, GI or Ovarian Tumor Antigen, Sialyl Lewis a)
Description:
Mucin glucoprotein is a sialyl Lewisa structure which is synthesized from type 1 blood group precursor chains and is present in individuals expressing the Lewis a and/or Lewis b blood group antigens. In normal tissues, sialyl Lewisa antigen is present in ductal epithelium of the breast, kidney, salivary gland, and sweat glands. Its expression is greatly enhanced in serum as well as in the majority of tumor cells in gastrointestinal (GI) carcinomas.

Applications:
Suitable for use in ELISA and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Immunohistology (Formalin/paraffin): 1:100. No special pretreatment is required for the immunohistochemical staining of formalin/paraffin tissues.
Optimal dilutions to be determined by the researcher.

Recomended Positive Control:
Colon carcinoma
