Raw materials for immunology

A harmonized component selection for optimal results


The utility of one assay component is relevant only when it works well with others.  Most products of our immunoassay portfolio were designed for existing diagnostic assays.

The portfolio features tested reagent configurations to meet every need and save development time. High-quality enzymes are complemented by substrates, antibodies can be coupled to a range of excellent marker enzymes, such as alkaline phosphatase, HRP, and ß-galactosidase, and key components are available in different forms — native, recombinant, inactive — to meet specific assay requirements.
