关于本试剂盒
The Human CA19-9 (Carbohydrate antigen19-9) ELISA quantitates CA19-9 in serum and plasma.
原理方法
The Human Carbohydrate antigen19-9 (CA19-9) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Carbohydrate antigen19-9 (CA19-9) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Carbohydrate antigen19-9 (CA19-9). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Carbohydrate antigen19-9 (CA19-9) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

靶标信息
Mucin glycoprotein is a Sialyl Lewis A 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 Lewis A 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.
