PEG

m-PEG-silane, MW 5,000 is a silane PEG polymer for surface modification through reaction between hydroxyl group and ethoxyl silane. The PEG spacer enhances water solubility of the compound. Reagent grade, for research purpose.

Biotin-PEG8-amine is a biotinylation reagent with a terminal primary amine group. The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. PEG8 arm increases aqueous solubility of the molecules conjugated to the biotin compound and 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.

endo-BCN-PEG3-amine is a click chemistry linker containing a BCN and an amine group. The BCN group can react with azide-tagged biomolecules under mile condition.

Azido-PEG11-t-butyl ester is a click chemistry linker containing an azide (N3) and a t-butyl ester moiety. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group is reactive toward alkyne, BCN, DBCO via Click Chemistry . The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG12-methane is a PEG linker that can react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. The PEG chain enhances the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG2-CH2CO2H is a short PEG linker. The terminal carboxylic acid cis reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc-protected amine can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG12-alcohol is a PEG linker containing a maleimide group and a hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. 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.
