Applicazioni

Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand and chelating agent with the ability to sequester divalent cations such as calcium and cesium. EDTA is used in a wide range of applications where the sequestration of divalent cations is required or useful. EDTA is used in the study of artificial restriction DNA cutters.

This tutorial review provides recent developments in artificial cutters for site-selective scission of DNA with the focus on chemistry-based DNA cutters. They are useful tools for molecular biology and biotechnology, since their site-selectivity of scission is much higher than that

Of more than 150 000 published studies evaluating new biomarkers, fewer than 100 biomarkers have been implemented for patient care. One reason for this is lack of rigorous testing by the medical community to validate claims for biomarker clinical relevance, and
