    Product Description

    DC4 crosslinker is a mass spectrometry-cleavable crosslinking reagent (18Å in length) that contains two intrinsic positive charges, which allow cross-linked peptides to fragment into their component peptides by collision-induced dissociation or in-source decay.1 Initial fragmentation events result in cleavage on either side of the positive charges so that cross-linked peptides can be identified as pairs of ions separated by defined masses.1 Additionally, these two intact peptide fragments can be further fragmented to yield a series of b- and y-ions for peptide identification.1

    WARNING This product is not for human or veterinary use.
