Propargyl-PEG6-t-butyl ester is a heterobifunctional linker consisting of an alkyne group and a t-butyl protected carboxyl group. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The t-butyl group can be hydrolyzed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
