Conveniently packaged extremely stable and highly sensitive ProteoSilver(TM) Plus Silver Stain Kit is an ideal product for any protein scientist. Similar to ProteoSilver (PROTSIL1) this kit contains prepared SOLUTIONons of silver staining reagents along with detailed instructions to achieve optimal results. With a detection limit of 0.1 ng/mm2 of protein (BSA) and an extremely low background ProteoSilver Plus leads to superior detection of low abundance proteins.ProteoSilver Plus is also MALDI-MS compatible and does not contain glutaraldehyde which crosslinks lysine residues resulting in inaccurate spectra. ProteoSilver Plus Silver Stain Kit contains two additional reagents for destaining an excised protein spot for those wishing to perform further characterization through tryptic digestion and MALDI-MS analysis.
