Abstract:
The present invention finds a media that can highly selectively retain proteins or peptides to be enriched/separated, as well as provides a method for selectively enriching/separating proteins or peptides using such a media. A method for enrichment/separation of a protein or a peptide, comprising separating a protein or a peptide containing an amino acid residue with a π electron-containing group by using a media with a π electron-containing group. Preferably, the amino acid residue is a tryptophan residue or a tryptophan residue modified with a sulfenyl compound, and the media is a media with phenyl group.
Abstract:
A communication system includes a transmitting device, a receiving device having receiving device for receiving data transmitted by said transmitting device and managing device for managing received data, detecting device for detecting whether or not communication of data between said transmitting device and said receiving device is permitted, said detecting device being provided with at least one of said transmitting device and said receiving device, wherein when said detecting device detects a fact that communication of data is permitted, said transmitting device starts transmitting data to said receiving device.
Abstract:
The present invention provides a method for chemically removing a N-terminal methionine residue selectively, specifically and efficiently from a peptide or a salt thereof having an optionally oxidized methinine residue at its N-terminal. The method reacts a peptide or a salt thereof having an optionally oxidized methinine residue at its N-terminal with an &agr;-diketone derivative, followed by hydrolysis.
Abstract:
A cysteine-free peptide is produced by producing a fused protein comprising a protein having cysteine at its N-terminal and a cysteine-free peptide ligated to the N-terminal and subsequently subjecting the fused protein to a reaction for cleaving the peptide linkage.
