SpecificityThis assay has high sensitivity and excellent specificity for detection of Mycobacterium Tuberculosis Antibody. No significant cross-reactivity or interference between Mycobacterium Tuberculosis Antibody and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between Mycobacterium Tuberculosis Antibody and all the analogues, therefore, cross reaction may still exist in some cases.

Product Description
specificalIntended Uses: This Mycobacterium Tuberculosis Antibody ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human Mycobacterium Tuberculosis Antibody. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay||Mycobacterium Tuberculosis Antibody ELISA kit applies the competitive enzyme immunoassay technique utilizing Mycobacterium Tuberculosis antigen and an Mycobacterium Tuberculosis Antibody-HRP conjugate. The assay sample and buffer are incubated together with Mycobacterium Tuberculosis Antibody-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the Mycobacterium Tuberculosis Antibody concentration since Mycobacterium Tuberculosis Antibody from samples and Mycobacterium Tuberculosis Antibody-HRP conjugate compete for the Mycobacterium Tuberculosis antigen binding site. Since the number of sites is limited, as more sites are occupied by Mycobacterium Tuberculosis Antibody from the sample, fewer sites are left to bind Mycobacterium Tuberculosis Antibody-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Mycobacterium Tuberculosis Antibody concentration in each sample is interpolated from this standard curve.
