t-Boc-Aminooxy-PEG3-bromide is a crosslinker containing a t-Boc-aminooxy group and a bromide (Br). The bromide (Br) is a very good leaving group for nucleophilic substitution reactions.Thet-Boc- aminoxy can be deprotected under mild acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media.
