Description

·         Used antigen: ASCA, MPO, DAG, tTG, IF, APCA

·         Antigens are applied in the form of microdots (spots) in triplets to a nitrocellulose membrane in a microtiter well format.

·         If specific antibodies are present in the sample, they will bind to the respective separate antigens.

·         The complex is labelled with Conjugate and detected through a colour reaction with Substrate (BCIP/NBT).

·         The kit enables 48 tests.

·         Short incubation periods, total assay time: approximately 1.5 h.

·         Each individual test includes control spots, which serves to check functionality of the kits, and also the spots for checking the presence of the conjugate.

·         Included positive controls enable validation of the tests.

·         For quantitative evaluation the wells contain calibration spots.

·         All reagents are supplied ready to use.

·         The kit may be used sequentially for smaller batches of samples (reagents are provided in sufficient quantities).

·         Evaluation using Microblot-Array reader and the appropriate software.

Applications

·         Confirmation for ELIA or other screening tests.

·         Identification of individual antibody types, differentiation of individual autoimmune liver diseases.
