BD Biosciences announced last week the launch of its DsRed-Monomer fluorescent protein. Derived from the Discosoma reef coral, DsRed-Monomer is ideal for multicolor applications in flow cytometry and fluorescence microscopy, the company said. The protein is very stable, which allows for monitoring of fluorescence over extended periods of time, the company added.

According to BD Biosciences, DsRed-Monomer is well tolerated by mammalian cells, and has been successfully used to create stably transfected, clonal cell lines.


QIAGEN announced this week the release of its Qproteome kits. Based on spin or gravity-flow columns, the kits enable fast, standardized fractionation of complex protein matrices for initial purification or preprocessing for PAGE or mass spectrometry analysis, the company said.

Kits separate proteins on the basis of glycosylation patterns, their subcellular localization, their affinity to nucleic acids, and their overall solubility. An additional kit is available for depletion of albumin and IgG from serum or plasma samples.
