A. Menarini Diagnostics works closely with industry experts to develop ourproprietary products, resulting in continuous expansion and updating of our product offering.

Enzyme-linked Immunosorbent Assay (ELISA) is a widely used method for monitoring and diagnosing diseases. Zenit Reagents is the brand name of the A. Menarini Diagnostics ELISA kits for researchers and in vitro diagnostics clinicians. Most kits utilizethe latest target antigens for detection with high sensitivity and specificity. Ready-to-use reagents (substrate, assay diluent, and stop solution) are included for easy operation. Flexible break-away microwells provide convenience and cost savings.

With over 20 years of leadership in ELISA technology, A. Menarini Diagnostics offers an impressive array of more than 50 different ELISA assays that feature accurate qualitative and quantitative detection of antibodies for the diagnosis of autoimmune diseases.

  • Antigens selected and presented in a highly purified form for the highest accuracy
  • Standardized component sets and methods for greater reproducibility
  • Optimal detection systems for enhanced sensitivity and specificity
  • Optimal design for performance on our automated ELISA platforms, such as Zenit UP
  • Choice of single or multiple point calibration for greater flexibility

Immunofluorescence microscopy is the cornerstone of autoimmune diagnostics.

Zenit IFA reagents offer a complete line of products for semi-quantitative detection of autoantibodies against various subcellular components including nucleic acids, nuclear proteins, and cytoplasmic proteins.

A. Menarini Diagnostics is recognized as a leader in innovating assays with the IFA technology. The use of digital scanners leverages the advantages of standardization in the reading and interpretation of such important substrates as HEp-2.

Our IFA products are formulated to work with modern digital scanners in the Zenit G-Sight series.

Zenit IFA reagents range: more than 20 complete IFA kits, and 50 different types of single slides.

Each component is rigorously optimized and provided in easy to use dropper vials. Our conjugates contain ideal F/P ratios to produce clear specific fluorescence. Counterstains are formulated to provide the best contrast and reduce background. Serum diluents stabilize antigen/antibody complexes and preserve ideal morphology to provide clear reactions. Our mounting medium is specifically formulated to preserve staining with minimal fading.

Quality is the hallmark of our IFA product range.
