Kinexus Bioinformatics of Vancouver, British Columbia, has added a new proteomics signal transduction protein profiling service to its offerings. The Kinetworks Cell Cycle Screen detects up to 30 cell cycle proteins in a model system. Kinexus also offers screening services for 75 protein kinases, 33 phosphoproteins, 25 phosphatases, 25 apoptosis proteins and 25 stress/heat shock proteins using as little as 300 µg of total cell or tissue lysate protein.

Biacore International of Uppsala, Sweden, has developed a MALDI plate holder and surface prep unit for its Biacore 3000 instrument that can automatically transfer samples from Biacore chips onto MALDI plates from Bruker Daltonics. The product, which results from a collaboration with Bruker, will be available to customers in the next few months.

Fluidigm of South San Francisco has launched its first product, a protein crystallization system called Topaz Crystallizer, which makes use of free interface diffusion. Disposable “fluidic microprocessors” with pneumatically actuated valves control the allocation and interaction of nanovolumes of reagents and protein solutions. Up to 5,760 crystallization conditions can be tested on 40 microprocessors using as little as 120 microliters of protein, according to the company.
