Molecular Devices said last week that it has introduced the Transil Membrane Affinity and Transil Human Serum Albumin Binding assay kits. According to MD, the Transil Membrane Affinity assay uses beads that are coated with a lipid bilayer that mimic interactions between compounds and cell membranes. The Transil HSA Binding assay contains beads that have been coated with human serum albumin and pre-dispensed into a microplate format, which increases throughput on the company's SpectraMax microplate readers.
