Mycobacterium Tuberculosis IgA ELISA (EIA) Kit Background Information
Mycobacterioses (tuberculosis, leprosy, atypical mycobacterioses, paratuberculosis, and perhaps
Crohn's Disease) are the infectious diseases of men and animals with the largest diffusion on earth. The infectious agents of tuberculosis are acid-resistant rod-like formed bacteria of the family Mycobacteriaceae, genus Mycobacterium. The germ was detected by Robert Koch in 1882. Owing to the very high infectious power of pathogenic mycobacteria, early diagnosis is essential to prevent spreading of the disease. Convergence of various approaches is necessary to control the mycobacterioses, immune reactions, and bacterial shedding during the diseases. The illness is normally transferred by droplets of saliva from infected persons. This ELISA test kit for the determination of IgA antibodies uses a cocktail of highly pure proteins in order to determine an immune response against the bacteria in human serum. A fresh or chronically active infection can be diagnosed by IgG and IgM tests, which are also available.




Mycobacterium Tuberculosis IgA ELISA (EIA) Test Principle
Mycobacterium tuberculosis antigen is bound on the surface of the microtiter strips. Diluted patient serum or ready-to-use standards are pipetted into the wells of the microtiter plate. A binding between the IgA antibodies of the serum and the immobilized Mycobacterium tuberculosis antigen takes place. After one hour incubation at room temperature, the plate is rinsed with diluted wash solution, in order to remove unbound material. Then ready-to-use anti-human-IgA peroxidase conjugate is added and incubated for 30 minutes. After a further washing step, the substrate (TMB) solution is pipetted and incubated for 20 minutes, inducing the development of a blue dye in the wells. The color development is terminated by the addition of a stop solution, which changes the color from blue to yellow. The resulting dye is measured spectrophotometrically at the wavelength of 450 nm. The concentration of IgA antibodies is directly proportional to the intensity of the color.




Mycobacterium Tuberculosis IgA ELISA Performance Characteristics
Intra-Assay Precision 7.9 %
Inter-Assay Precision 7.4 %
Inter-Lot-Precision 5.7 8.9 %
Analytical Sensitivity 1.34 U/ml
Recovery 87 96 %
Linearity 78 111 %
Cross-Reactivity No cross-reactivity to Helicobacter pylori and Bordetella pertussis
Interferences No interferences to bilirubin up to 0.3 mg/mL, hemoglobin up to 8.0 mg/ml & triglycerides up to 5.0 mg/ml




Precautions on Mycobacterium Tuberculosis IgA EIA Test Kit
All sera and plasma or buffers based upon, have been tested respective to HBsAg, HIV and HCV with recognized methods and were found negative. Nevertheless precautions like the use of latex gloves have to be taken.
