Safety Data Sheets

This cleavable trifunctional biotinylating reagent incorporating a cleavable linker is highly valuable for usage in protein enrichment. A linker based on the Dde protecting group leads to efficient release of protein targets under mild aqueous buffered conditions with 2% hydrazine. The cleaved moiety that remains on the modified peptide only minimally changes the peptide mass and generates an additional positive charge, which facilitates peptide sequencing by ETD.
