Biotin-PEG4-alkyne is a PEG linker containing a biotin group and a terminal alkyne. Biotin is useful for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins while terminal alkynes are used in copper (I) click chemistry with azides to form stable triazoles with a target molecule. The inclusion of a PEG linker in this molecule improves its aqueous solubility.
