Biotin-PEG-Mal

Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R₁-(O-CH₂-CH₂)_n-O-R₂. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation.

Biotin-PEG-MAL is a linear heterobifunctional reagent with a biotin and a maleimide.

Store between 0 and -5 C. Avoid exposure to light. Ensure the vial lid is sealed when not in use.
