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.Primary antibodies are available purified, or with a selection of fluorescent CF\u00ae Dyes and other labels. CF\u00ae Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF\u00ae405S and CF\u00ae405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.<\/p>\n<div style=\"margin:18px 0 4px;padding:11px 14px;background:#fdf4f4;border:1px solid #e6bdbd;border-left:3px solid #c41e3a;border-radius:4px;font-size:13px;line-height:1.55;color:#3a3a3a;\"><strong style=\"color:#8a1524;\">For Research Use Only (RUO).<\/strong> This product is sold strictly for laboratory research use only. <strong>Not for human or veterinary consumption, therapeutic, or diagnostic use.<\/strong> Any pharmacological, therapeutic, cosmetic, or biological effects described above are provided as research context only and do not represent intended or approved uses of this product.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>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.
