SRU Biosystems, Molecular Probes


SRU Biosystems has announced the launch of its BIND system for drug discovery applications.

According to SRU, BIND enables label-free detection of biomolecular interactions. The system comprises the company's BIND Reader and 96- or 384-well microplate biosensors. The platform is based on a patented optical effect using a proprietary, nanostructured optical grating to provide sensitive measurement of binding on the biosensor surface, SRU said.

The BIND system can be used to measure biomolecular interactions involving proteins, peptides, or cells the company said. The instrument has potential applications in therapeutic antibody development, affinity ranking with antigen and functional screening with cells, peptide epitope mapping, and immunogenicity screening, SRU said.

Molecular Probes, a subsidiary of Invitrogen, has announced the release of SlowFade Gold, an antifade reagent designed to improve the quality of fluorescence microscopy images. According to Molecular Probes, SlowFade Gold increases the stability of fluorescent signals, thereby extending the time available for imaging.

The reagent joins Molecular Devices' ProLong Gold antifade reagent, which is more sutiable for longer term imaging applications, the company said. SlowFade Gold does not cure over time, allowing samples to be viewed immediately after mounting, Molecular Probes said.

Both antifade reagents are supplied as 10 ml of ready-to-use solution.

In addition, Invitrogen said that it has released Vivid Colors Emerald Green and Yellow fluorescent proteins, the first in a series of fluorescent protein vectors based on the jellyfish Aequorea victoria.

Invitrogen said that particular mutations that conveyed no performance advantage have been eliminated to minimize licensing requirements.
