Invitrogen, Proxeon

Premium
Invitrogen this week launched iGene, a platform allowing researchers to search for experimental reagents by gene or protein. iGene is the latest member of Invitrogen’s online scientific resource collection which includes the iProtocol Online Library and   iPath Online Bioatlas.
 
The company also launched the Premo cameleon calcium sensor, a genetically encoded fluorescent protein-based sensor for detecting calcium levels in live cells for cell signaling studies. The sensor provides “ratiometric read-out at visual excitation wavelengths in the presence of calcium and interferes minimally with cell physiology,” Invitrogen said in a statement.
 

 
Proxeon this week released its ProteinCenter, version 1.1, a Web-based application that allows researchers to integrate experimental biology data with the contents of public protein databases. In a statement, the company said ProteinCenter facilitates the mining of proteomics data quickly, removes redundancy, and allows for the comparison of data sets and the instant biological overview of large data sets.
