Latest Patents

Lotti holds a patent for a method and apparatus for the identification and quantification of biomolecules. This innovative technology involves electroblotting polypeptides through a digestion membrane to a composite capture membrane. The process allows for direct analysis using mass spectrometry. The molecular weights of the fragments generated are utilized to identify the originating polypeptide. The digestion membrane contains an immobilized protease, such as trypsin, which efficiently cleaves the polypeptides into fragments. This method ensures that a single pass through the membrane is sufficient for effective analysis. The peptide fragments are then collected onto a chemically treated composite capture membrane, enhancing sensitivity for subsequent analysis by MALDI-TOF mass spectrometry. This technology has a wide range of applications, including the identification of proteins separated on gels or within tissue samples.
