Description
CA19-9, a carbohydrate epitope expressed on a high MW (>400kDa) 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.
Reactivity
Human
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) were used as the immunogen for the CA19-9 antibody.
Clonality
Monoclonal
Clone
121SLE
Conjugation
Unconjugated
Purification
PEG precipitation
Dilution
Immunohistochemistry (FFPE) : 1-2ug/ml for 30 min at RT
Storage Conditions
Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
Notes
For research use only.
Applications Notes
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 tissues2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
