PEG

Ms-PEG2-t-butyl ester is a PEG linker containing a mesyl group and a t-butyl protecting group. The mesyl group is a good leaving group for nucleophilic substitution reactions. The t-butyl is an acid labile protecting group. Upon removal, the carboxylic acid can react with primary amines. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Ald-Ph-PEG4-NHS ester is a PEG linker containing a benzaldehyde moiety and an NHS ester that is very reactive with NH2 -containing molecules.. The benzaldhyde can react with aminooxy-containing molecules. PEG4 spacer increases the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG4-alcohol is a aqueous soluble PEG reagent containing an azide group and a terminal hydroxyl group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DNP-PEG4-acid is a PEG linker containing a DNP and carboxylic acid moiety. DNP is involved in biological applications such as participating in ion transport across membranes.
