特徴

• Sample Type:Serum, plasma
• Intended Use:For the quantitative determination of human carbonhydrate antigen 19-9 (CA19-9) concentrations in serum, plasma.
• Sensitivity:2.5U/ml
• Range:10-150U/ml
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with antibody specific for CA19-9. Standards and samples are pipetted into the wells with a Horseradish Peroxidase (HRP) conjugated antibody specific for CA19-9 and incubated. Following a wash to remove any unbound reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CA19-9 bound in the initial step. The color development is stopped and the intensity of the color is measured.
• Specificity:This assay has high sensitivity and excellent specificity for detection of human CA19-9. No significant cross-reactivity or interference between human CA19-9 and analogues was observed.
