Détail du produit anti-CA 19-9 anticorps

Purification: PEG precipitation

Immunogène: 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) were used as the immunogen for the CA19-9 antibody.

Isotype: IgM kappa

Information d'application

Indications d'application: Optimal dilution of the CA19-9 antibody should be determined by the researcher.

1. No special pretreatment is required for the immunohistochemical staining of formalin-fixed, paraffin-embedded tissues

Détails sur CA 19-9

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

Autre désignation: CA19-9

Sujet: 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.
