CA 19-9 antibody

Catalog No. ABIN6941326

Product Details anti-CA 19-9 Antibody

Target: CA 19-9 (Gastrointestinal Cancer Antigen CA19-9 (CA 19-9))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CA 19-9 antibody is un-conjugated

Application: Immunohistochemistry (IHC), Staining Methods (StM)

Specificity: CA19-9, a carbohydrate epitope expressed on a high MW (400 kDa) mucin glycoprotein, is a sialyl Lewisa structure which is synthesized from type 1 blood group precursor chains and is present in individuals expressing the Lewisa and/or Lewisb 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, including adenocarcinomas of the stomach, intestine, and pancreas. Preoperative elevated CA19-9 levels in patients with stage I pancreatic carcinoma decrease to normal values following surgery. When used serially, CA19-9 can predict recurrence of disease prior to radiographic or clinical findings. This MAb is excellent for staining of formalin-fixed, paraffin-embedded tissues.

Immunogen: Precipitin lines obtained after immuno-diffusion using MAb 116-NS-19-9 and mucins isolated from an ovarian cyst of a Lewis A+B- patient (0Le).

Clone: 121SLE

Isotype: IgM kappa
