New Products

Sigma-Aldrich announced last week the availability of its Panorama Human Kinase v1 Array. The array contains 152 commonly studied kinases and uses a fusion tag attached to each kinase to tether and uniformly orient proteins on the array surface, the company said.

The new array is the latest in Sigma's Panorama Protein Array product line, which includes arrays of proteins, antibodies, peptides, and tissue extracts.

GE Healthcare introduced last week the Ettan nanoLC, a one-dimensioanl nanoscale peptide separation system.

The Ettan nanoLC performs high-pressure gradient formation and real-time gradient monitoring while maintaining a continuous flow to the ion source or MALDI spotter throughout a run, GE said. The instrument's low dead volumes help ensure minimum peak broadening and consistent peak concentrations.

GE Healthcare also launched last week Capto S, a strong cation exchange media designed for high-throughput capture of recombinant proteins and intermediate purification of antibodies at process scale.

Capto media are based on a high flow agarose with high rigidity and high binding capacity. The media enables faster purification, GE said.


Movers & Shakers

George Grills has taken the position of director of advanced technology assessment and director of operations of life sciences core facilities at Cornell University Institute for Biotechnology and Life Science Technology.

Grills was formerly director of DNA sequencing at Harvard-Partners Genome Center.

Sam Gambhir has become a director at Lumera, the company said this week.

Gambhir is a professor in the nuclear medicine division at Stanford University School of Medicine and as the director of the school's molecular imaging program.
