proteases
A selection of specific proteases are available that are designed for use in peptide fragmentation for mass spectronmetry analysis or protein sequencing. G-Biosciences offers the following proteases:
MSG-Trypsin™
A highly stable masss spectrometry grade trypsin. MSG-Trypsin™ was stored at -20º C, -70º C and room temperature for six months and then resuspended and analyzed by SDS-PAGE and stained with FOCUS FastSilver™. Compared with a competitor's trypsin, only the MSG-Trypsin™ stored at room temperature and the competitor's trypsin showed degradation products.
