PEG

Biotin-PEG6-Mal is a maleimide biotinylation linker that can react with sulfhydryl groups (at pH 6.5-7.5) specifically to form a thioether linkage. The hydrophilic PEG spacer increases aqueous solubility of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG2-CH2CO2tBu is a PEG linker containing a benzyl group and a t-butyl protected carbonyl. Both the benzyl and t-Butyl group can be removed under acidic conditions. The carboxylic acid can be reacted with primary amines in the presence of activators such as EDC and DCC to form stable amide bonds. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
