PEG

Bis(m-PEG4)-N-OH is a PEG linker which contains two PEG spacers connected by an -NOH group. The hydrophilic PEG spacers increase the compounds water solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG5-CH2CO2-NHS is a very active pegylation reagent with 5 PEG units. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group allows the reaction with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG10-alcohol is a aqueous soluble linker regent containing an click chemistry azide group and a terminal hydroxyl group. 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.

m-PEG3-(CH2)3-alcohol is a PEG linker containing a hydroxyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG4-CH2CO2-NHS has a propargyl group and an NHS group. This reagent is amine reactive, thus, useful for derivatizing biomolecules with amine group. The propargyl group reacts with azides via copper catalyzed azide-alkyne Click Chemistry to form stable triazole bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-CH2CO2-NHS is an amine reactive linker with an alkyne moeity which can react with azide-bearing biomolecules in copper catalyzed Click Chemistry reactions. The PEG units enhance the solubility of the linker in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG5-CH2CO2H is a water soluble PEG linker. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG8-CH2CO2H is a aqueous soluble PEG linker. The hydrophilic PEG spacer increases solubility in aqueous media. Azide (N3) group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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. Please contact us for GMP-grade inquiries.

Azido-PEG5-CH2CO2-PFP is a PEG linker that contains an azide and a PFP group with one carbon between PEG arm and PFP ester group. The azide group can undergo copper-catalyzed Click Chemistry reactions to react with alkynes. The PFP group can react with amines to form stable bonds. PFP moieties are also less susceptible to undergo hydrolysis. The hydrophilic PEG spacer increases the water solubility of the compound. Longer PEG chains enhance the water solubility properties of the chain. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
