Thermo Fisher Scientific this week released its new Pierce GTPase Enrichment Kit for profiling GTPases and G-protein subunits in tissues, cells, and subcellular proteomes.
The kit uses desthiobiotin-nucleotide probes that enable easy reversal of the capture bond by biotin displacement, low pH, or heat, allowing for study of the isolated proteins via Western blot or mass spec, the company said.
Pressure BioSciences this week introduced four new products it plans to release between 2011 and 2013.
