Pegylation & PEG Linkers
Polyethylene glycol (PEG) linkers are necessary for bioconjugation and pegylation. Lumiprobe offers a range of PEG based products with different linker lengths, bearing various reactive groups.
Bifunctional linker with terminal alkyne function, and carboxylic acid moiety, CAS# 1415800-32-6.
Alkyne-PEG3-OH is a triethyleneglycol based bifunctional linker with a hydroxyl group and an alkyne fragment.
A bifunctional linker molecule containing both terminal alkyne moiety for Click chemistry, and amine group. Contains a long hydrophilic PEG4 arm.
Water soluble, heterobifunctional hydrophilic linker with a length of 14 Å, containing maleimide for thiol labeling, and alkyne for Click chemistry. An ideal reagent to attach an alkyne moiety to a protein.
A bifunctional linker with azide and amine groups flanking PEG3 (triethylene glycol)
Triethylene glycol diazide (CAS# 59559-06-7) is a bifunctional crosslinker bearing two azide groups. Suitable for Click chemistry.
PEG3 dicarboxylic acid
PEG3 dicarboxylic acid is a bifunctional linker carrying two carboxy groups. It contains a polyethyleneglycol-3 linker between the carboxyls.
PEG3 tetrazine is a mono-reactive triethyleneglycol with a tetrazine group for ied-DA conjugation with strained olefins.
