- EUROPLUS™ ANA Mosaic 20 (HEp-2 cells, primate liver, SS-A+SS-b BIOCHIPs, rib. P-prot.+Jo-1 BIOCHIPs: antibodies against SS-A/SS-B.
- Screening testfor the detection of antibodies against cell nuclei (ANA).
- Indications: rheumatic diseases.
- Initial dilution 1 : 100; conjugate class anti-human IgG, FITC-labelled.
- Using HEp-2 cells many antibodies against cell nuclei can be analyzed, e.g. antibodies against DNA, histones, RNA, nRNP, Sm, SS-A, SS-B, nuclear dots, centromeres, nuclear membrane, nucleoli (PM-Scl, fibrillarin, RNA polymerase I, NOR), Scl-70, cyclin I and II, spindle fibers, midbody, centrioles.
- In addition, cytoplasmic autoantibodies are identified with HEp-2 cells: antibodies against ribosomes, Jo-1, mitochondria, Golgi apparatus, actin etc.
- The primate liver permits the verification of results between both substrates, makes the pre-differentiation of a large number of ANA possible, and helps to establish titer levels. Moreover, the primate liver often contains additional antigens, allowing the identification of further autoantibodies: antibodies against LMA, LSP, endomysium, bile ducts and endothelium cells, as well as cANCA und pANCA.
- The EUROPLUS™ system is a monospecific test that can be used to confirm the presence of autoantibodies against cell nuclei and cytoplasm components with one and the same test kit. The following antigens are currently available as EUROPLUS™ BIOCHIPs: SS-A, SS-B, nRNP/Sm, Sm, Jo-1, ribosomal P-proteins.
- HEp-2010: antibodies against spindle fibers.
- Screening test for detection of antibodies against cell nuclei.
- Indications: rheumatic diseases.
- Initial dilution 1 : 100; conjugate class anti-human IgG, FITC-labelled.
- Compared to standard HEp-2 cells, HEp-20-10 cells demonstrate 10-fold more mitotic cells. Antibodies against mitotic-specific structures (centromeres, spindle fibers, midbody, centrioles, NOR) can be more easily identified than with conventional preparations.
- At the same time, the cell line HEp-20-10 offers the full antigen spectrum for cell nuclei antibody diagnostics.
- The BIOCHIP with HEp-20-10 can be supplemented with additional substrates, for example, primate liver (ANA; Order No. FA 1512-####-1 G) as well as rat kidney and rat stomach (Order No. FA 1802-####-3 G).

- Incubated EUROLINE-WB HEp-2 Cell Antigens plus SS-A, Ro-52 and CENP B.
- Differentiation of antibodies against cell-nuclear and cytoplasmic antigens.
- Indications: Sharp syndrome (MCTD), systemic lupus erythematosus, Sjögren’s syndrome, progressive systemic sclerosis, poly/dermatomyositis, PBC.
- EUROLINE-WB is a combination of westernblot and line blot techniques. Proteins from a whole antigen extract of HEp-2 cells are electrophoretically separated according to molecular mass and transferred onto a nitrocellulose membrane. A membrane chip coated with highly purified native SS-A, recombinant Ro-52 and recombinant CENP B is then added to the westernblot strips.
- Antibodies against SS-A are characteristic markers for SLE and Sjögren’s syndrome. In contrast, antibodies against Ro-52 also occur in patients with other autoimmune diseases. EUROLINE-WB contains both antigens next to each other at defined positions, in addition to the complete HEp-2 antigen spectrum of the Westernblot. The use of native SS-A increases the sensitivity, since 37% of antibodies against SS-A do not show any reaction with the denatured antigen from the Westernblot
- Serum dilution 1 : 50, conjugate class anti-human IgG, AP-labelled.
- Antigens: SDS extract from HEp-2 cells (whole antigen), highly purified native SS-A from calf thymus, recombinant Ro-52 and CENP B.
