GE Healthcare this week launched the illustra triplePrep for the simultaneous isolation of total denatured protein and genomic DNA and RNA from a single undivided sample in less than one hour.

The kit contains two spin columns and six optimized buffers for use with mammalian cell culture or animal tissue. The kit offers time-savings of up to 70 percent compared with traditional methods of splitting the sample and carrying out three individual extractions, the company said in a statement. It also allows for more data to be generated from small amounts of materials.

High-quality and high yield protein, DNA, and RNA can be isolated from tissue types such as liver, kidney, brain, and intestine, and cell lines HeLa, NIH-3T3, and HEK-293, GE Healthcare said.

Invitrogen, a division of Life Technologies, this week launched the BenchPro 4100 Western Processing Device for the automated processing of routine washing and incubation steps for standard laboratory procedures.

The instrument simplifies protein analysis workflows by automating Western blotting, the company said in a statement.

The BenchPro 4100 was designed with Western blotting in mind and completely automates the hands-on, three-hour process. The device is part of a workflow that includes the BenchPro 4100 Card Processing Station and the BenchPro 4100 Western Cards.

German firm Caprotec Bioanalytics this week announced the launch of the SAH caproKit and cAMP caproKit, the company's first two caproKits, which are designed for research into small molecule-protein interactions.

The kits are based on Caprotec's Capture Compound Mass Spectrometry technology, which enables direct isolation and identification of selected compounds, including membrane proteins, from a complex sample [See PM 12/06/07].

The SAH caproKit allows researchers to discover, identify, and characterize proteins that interact with S-adenosyl-L-homocysteine and S-adenosyl-L-methionine. The cAMP caproKit enables discovery, identification, and characterization of proteins that interact with cyclic adenosine monophosphate.

Orders have been placed for the kits and Caprotec has begun shipping them, it said in a statement.

Cell Biosciences this week launched its first kits for the analysis of oncoproteins MEK and ERK on its Firefly 3000 Protein Analysis System.

The kits are the company's first for analysis of the proteins, which play critical roles in cancer cell survival and proliferation. Use of the kits on the Firefly allows detailed profiles of MEK and ERK signaling in as few as 25 cells, the company said in a statement.
