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.
The products are the Barocycler HUB440 – a high pressure generator for a variety of sample prep applications to be released in Q3 2011; the Barocycler FFPE Protein Extraction Service – a service using pressure cycling for the extraction of proteins from formalin-fixed, paraffin-embedded samples to be launched in 2012; the XstreamPCT HPLC Digestion Module – a PCT-enhanced protein digestion system and the first module in the company's pressure cycling based HPLC system; and the Barocycler HT Multiwell – a device for pressure cycling enhanced biomolecule extraction and enzymatic digestion.
