Beckman Coulter announced this week the availability of its second-generation ProteomeLab IgY-12 partitioning chemistries. The new chemistries dramatically increase the throughput capacity of columns, which are designed to selectively partition 12 highly abundant proteins from human or primate serum or plasma, the company said.
According to Beckman, each column can now partition 20 to 250 microliters per cycle about twice as much plasma or serum per cycle as the original version.
Applied Biosystems and joint venture partner MDS Sciex announced this week the availability of the Enhanced Validation Package for Analyst 1.4.1 Software. The software is designed to guide users through the process of validating ABI/MDS Sciex's Analyst 1.4.1 Software, which is used with the companies' triple quadrupole and linear ion trap mass spectrometry systems.
Software validation is a process that is necessary for maintaining compliance with federal GLP or 21 CFR Part 11 guidelines. The Analyst 1.4.1 Software Enhanced Validation package was developed in response to customers' requests for faster, easier, cheaper transitions to system upgrades, said ABI/Sciex.
Millipore announced this week that its Millipore Express Plus membrane is now available in cut disk format for use in reusable filter holders.
Millipore's Express Plus membranes consist of polyethersulfone. They provide fast filtration of tissue culture media, additives, buffers, and other aqueous solutions, with low protein binding, the company said.
The membranes are now available as 25 mm and 47 mm cut disks with 0.22 micrometer and 0.45 micrometer pore sizes.
