ProteaseArrest
Protease inhibitor cocktail
ProteaseArrest™ from G-Biosciences/Genotech, St Louis, is a general protease inhibitor cocktail solution that is provided as a 100X concentrated, ready-to-use solution that inhibits more than 95% of protease activity, even in tissues known to have higher-than-normal protease activity. Due to the optimized concentration of the various inhibitors, it inhibits protease activities and is suitable for the protection of proteins during preparation of samples and protein purification from animal tissues, plants, yeast, and bacteria. The product is available as a single-use aliquots, OneQuant™ ProteaseArrest, that are suitable for >95% protease inhibition in 10-ml solutions for greater convenience. In addition to the single-use aliquots, several formats are available that require no dissolving or resuspension.

OneDrop
Microporation system
The OneDrop system from BTX, Holliston, Mass, makes difficult-to-transfect cells easier, including MEF, brain astrocytes, and stem cells (hMSC). Protocols have yielded >91% transfection efficiency. The new technology does not use standard cuvettes, but instead relies on a patented sampling capillary as the electroporation chamber. The system generates a uniform electric field in the tip, making the pipette tip functionally equal to an electroporation cuvette.

NAP-BLOCKER
Nonanimal protein blocking agent
NAP-BLOCKER™ from G-Biosciences/Genotech, St Louis, is a nonanimal protein-blocking agent for immunodetection assays such as Western blots, dot blots, and ELISA. It is free from biotin and other cross-reacting agents present in most of the animal-source blocking agents, helping to ensure uniform blocking without nonspecific binding. The product is supplied as a premade [2X] solution; users dilute with any buffer and block nitrocellulose or PVDF membranes. The presence of animal proteins can lead to high nonspecific backgrounds as antigens and antibodies. The product ensures no cross-reaction with users’ animal-source antigens and antibodies, because it is 100% free of animal proteins.
