Introduction• The Universal Linkage System (ULS™) is a platinum-based technology that allows direct labeling of proteins and nucleic acids with a large variety of labels and haptens, including many fluorophores, biotin, and dinitrophenol.
• In proteins, ULS™ forms a stable coordinative bond with the sulfur atom in Methionine and free Cysteine, and with a nitrogen in Histidines (Fig. 1).
• Is an easy and robust labeling method
• Provides high coverage of proteome
• Is stable in aqueous solution
• Labeling is compatible with a wide range of buffers and detergents including Tris, Glycine, SDS, Triton X-100, NP-40 etc.
CiPA Phase 2 Study: validation of an automated microelectrode array (MEA) assay of hiPSC-derived cardiomyocyte electrophysiology for cardiac safety evaluationPoster
These results support the use of hSC-CM and MEA technology for preclinical assessment of proarrhythmic risk within the proposed CiPA paradigm, and, more generally, demonstrate that automation of the CM-MEA assay can achieve high reliability and throughput for cardiac risk assessment in vitro.READ MORE
