SRU Biosystems this week introduced its Cartridge Reader based on 8- and 16-well biosensors. The Cartridge Reader is being offered as the company's entry-level instrument for assay development and low-throughput applications for cellular and biochemical studies, the company said.
 
The cartridges use SRU’s BIND label-free biosensor technology, which supports the use of 8-, 16-, 96-, 384-, and 1,536-well microplates.
 

 
Corning has introduced its automated liquid-handling accessory that integrates with Corning’s Epic system for high-throughput, label-free assays.
 
The Epic LHA includes a 384-well pipettor, a microplate stacker that can handle up to 20 lidded 384-well microplates, and an automated tip wash station. The liquid-handling system has been designed to maintain thermal stability in order to eliminate artifacts from laboratory temperature fluctuations.
 

 
Cellix has launched the VenaEC biochip, the company announced this week.
 
The VenaEC biochip is the second generation biochip to Cellix's Vena8 biochip. As with the Vena8 biochip, a range of suspension cell samples may be used with the VenaEC including T-cells, monocytes, neutrophils, eosinophils, platelets, and whole blood (heparanized). Compatible with both the VenaFlux and Microfluidic SP platforms, the VenaEC Biochip can be used to produce IC50 curves under shear stress conditions mimicking physiological flow.
 
Each VenaEC biochip comprises one top plate and four substrates that can be assembled in a custom-made frame for inverted microscopes. The top plate contains two microcapillaries in which each tissue culture-treated substrate enables the seeding and culturing of a variety of endothelial cells. Minimum cell sample volume is 10 mL, so the VenaEC biochip is appropriate for studying rare cell types or low sample volumes. Shear stress ranges from 0.05 - 100 dyne/cm2 in steps of 0.05 dyne/cm2 using Cellix's Mirus nanopump, which is part of the VenaFlux platform.
 

VenaEC biochips are sold in packs of 10, facilitating 80 experiments.
