1. Furthermore typical immunoassays use recombinant peptides rather than discrete peptide antigens. 2. Complex serological techniques have been developed into what are known as Immunoassays . 3. Multi-step assays are often called separation immunoassays or heterogeneous immunoassays. 4. Multi-step assays are often called separation immunoassays or heterogeneous immunoassays . 5. The use of a calibrator is often employed in immunoassays . 6. Fluorogenic reporters like phycoerythrin are used in a number of modern immunoassays . 7. Protein microarrays are a type of immunoassay that often employ fluorogenic reporters. 8. Latex, usually styrene-based, is also used in immunoassays . 9. It supplies antibody related products such as immunoassays ( e . g. 10. Traditional virus diagnostic procedures are being replaced by sensitive immunoassays with lanthanides.
