TTP LabTech s Acumen Explorer 405-nm Microplate Cytometer and NoAb BioDiscoveries ZeroTrap Microwell Plates


TTP LabTech has introduced its Acumen Explorer 405-nm microplate cytometer. The new instrument features a single violet laser excitation source, and enables use of the beta-Lactamase and blue fluorescent protein reporter systems. The company says the instrument offers multi-parametric analysis at high throughput for rapid, high-content assays. The company also said that the cytometer offers enhanced compatibility with quantum dots by increasing the intensity of fluorescence emission by up to four-fold compared to an earlier version of the instrument.

NoAb BioDiscoveries has launched its ZeroTrap microwell plates for homogenous biochemical or cellular assays with greatly reduced non-specific binding, the company said. The 96- and 384-well plates feature a proprietary surface-treatment technology for reducing non-specific binding of proteins, peptides, nucleic acids, and lipophilic small molecules to the plate while conducting assays. The company said the treatment can be applied to virtually any microwell plate, including polystyrene, polypropylene, polycarbonate, and glass.
