New Products

Greiner Bio-One and Scienion have launched a new protocol and buffer system for the production and analysis of protein microarrays. The system is specifically designed for use with the HTA Slides from Greiner Bio-One.

The system consists of four buffers and a detailed protocol for conducting protein experiments optimally using HTA Slides. According to the companies, the sciSPOT-PROTEIN print buffer allows users to achieve a homogenous protein bond to the surface of the HTA Slides, while the sciBLOCK buffer removes unbound proteins after spotting and saturates the HTA surface. Subsequently, the sciBIND buffer creates optimal conditions for a binding reaction, and finally, unspecific or non-bound sample material can be washed away with the sciWASH-Pro buffer.

TeleChem International has added dehumidification and interstitial printing features to its NanoPrint protein microarray spotters, the Sunnyvale, Calif.-based firm said last month.

TeleChem claims that the upgraded NanoPrint now has the first "fully active humidity control system to both add and remove humidity from the microarraying chamber." The interstitial printing feature combined with the humidification system will allow users to print higher density arrays, TeleChem said.

GE Healthcare last week introduced its ECL Plex detection system for "simultaneous multi-wavelength" protein expression analysis on Western blots using Cy3 and Cy5 fluorescent dye labels, the company said in a statement. The system is designed for multipurpose imagers, rather than a specialized device, the company said. The ECL Plex provides "increased reproducibility and sensitivity" protein expression quantification, and uses direct fluorescence detection without enzyme substrate amplification, GE said. In the multiplex application, two proteins can be detected with minimal cross-reactivity between antibodies, the company added.


Movers & Shakers

The Indiana Centers for Applied Protein Sciences has hired Jeffrey Billig as its new chief financial officer. INCAPS is a fee-for-service contract research organization that provides proteomic technology validation and protein analysis services for academic and private sector clients.

Billig comes to INCAPS from the Mitchel Group, where he was vice president and chief financial officer. He received his MS in management from the Purdue University Krannert School of Business.
