Product news
Thermo Fisher Scientific has announced the availability of the Thermo Scientific PageBlue Protein Staining Solution. This unique solution uses the colloidal properties of coomassie G-250 dye to stain proteins in polyacrylamide gels and on polyvinylidene (PVDF) membranes.
The solution exhibits a dynamic range of 5 to 500 nanograms, and is 10-times more sensitive than typical coomassie R-250-based stains.
The ready-to-use PageBlue Protein Staining Solution requires no protein fixation or special destaining steps. It contains no methanol or acetic acid, making it safer to use.

Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.
