Intended Use
The TUB IgA ELISA is an in-vitro microtiter plate based Enzyme assay for the quantitative detection of human IgA antibodies to Mycobacterium tuberculosis in serum or plasma within 100 minutes.
Contents of Kit

2. Sample Diluent: 100 mL, ready-to-use, in PE-vial, PBS/BSA buffer, contains 0.05% 5-bromo-5-nitro-1.3-dioxane.
3. Wash Buffer, 10× concentrate: 60 mL, in PE-vial, PBS buffer with Tween 20, contains 0.05% 5-bromo-5-nitro-1.3-dioxane.
4. 4 standard solutions: 2 mL each, ready-to-use, in PE-vials, with different amounts of relevant specific antibodies against Mycobacterium tuberculosis, contains 0.05% 5-bromo-5-nitro-1.3-dioxane.
5. Anti-human-IgA-conjugate solution: 12 mL, ready-to-use, in PE-vial, contains 0.05% 5-bromo-5-nitro-1.3-dioxane.
6. TMB substrate solution: 12 mL, ready-to-use, in PE-vial (black), contains a solution of tetramethylbenzidine (TMB).
7. Stop-solution: 12 mL, ready-to-use, in PE-vial, 0.2 M H2SO4.
Storage
Store the test at 2 - 8°C. Unopened kit components are stable until the expiry date. The expiry date is printed on the labels of the aluminum pouch (microtiter plate), on the labels of the containers for the liquids and on the outer packaging.
Do not use if the aluminum pouch is damaged. DO NOT FREEZE or expose temperatures above 30°C (except wash buffer, if crystal precipitate occurs).
Aluminum pouch with microtiter plate: Keep the test in unopened aluminum bag at 2 - 8°C.
Opened aluminum pouch with microtiter plate: Use up microtiter plate within 6 months!
Liquids: Keep liquid components at 2 - 8°C. Unopened liquids are stable until the expiry date. After first opening the liquids are stable for 6 months, if the bottles are tightly closed after every usage.
General Description
Human tuberculosis (TB) has become a global disease with its re-emergence in the Western countries in the last decades. According to WHO, more than 30 % of the world's population is estimated to be infected with the TB bacterium, Mycobacterium tuberculosis. TB is predominantly a disease of the respiratory tract, but can also affect other organs. People who are suffering from active pulmonary tuberculosis are highly infectious. TB kills yearly about 2 million people. Although, the TB bacterium was identified more than 100 years ago, the diagnostic methods, which are currently available, suffer from high price, poor sensitivity and specificity and are time consuming. The diagnosis of TB is usually made based on a combination of several laboratory tests.
The TUB IgA ELISA is suitable for the quantitative detection of human IgA antibodies to Mycobacterium tuberculosis within 100 minutes.
