PEG

endo-BCN-PEG4-PFP ester is a click chemistry reagent containing a PFP ester and a BCN group. PFP esters have similar applications as the NHS esters, but are more stable in aqueous solution. They can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group cais reactive with azide-tagged molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

endo-BCN-PEG2-acid is a PEG linker containing a BCN group and a terminal carboxylic acid. The BCN group can react with azide-tagged biomolecules. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

t-Butyl 1,5-di(ethoxycarbonyl)pentan-3-ylcarbamate is a branched molecule with an n-Boc group and two ethyl ester moieties. The Boc-protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG3-t-butyl ester is a PEG linker containing a maleimide group and a t-butyl ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose.
