Coupling TLC plates to mass spectrometry is a new field of high interest, which will contribute strongly to the progress of planar chromatography. The MS-grade plates are much cleaner than standard TLC/HPTLC plates providing higher sensitivity and reduced background signals. This allows trace analysis with mass spectrometry detection in lower nanogram range.

Trypsin is a serine endopeptidase that specifically cleaves peptide bonds on the carboxy side of s-aminoethyl cysteine, arginine and lysine residues and typically there is little or no cleavage at arginyl-proline and lysyl-proline bonds. The distribution of these residues in proteins allows trypsin digestion to produce peptides that are readily identified by mass spectrometry.

Protein-OUT™ is a washing solution that cleans plastic and glassware used in the proteolytic digestion and peptide isolation for mass spectrometry analysis. The rinsing of plastic and glassware with Protein-OUT™ will remove interfering chemicals and peptides that can leach from the tube walls and interfere or suppress the mass spectrometry signal. In addition, rinsing with Protein-OUT™ removes inadvertent contamination with dust and keratin.
