PEG

Bis-PEG3-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids 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.

Amino-PEG4-alcohol is a very popular PEG reagent containing an amino group (NH2) with a hydroxyl group (OH). The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. 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.

Amino-PEG5-azide is developed as a bifunctional PEG reagent with great solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-boc-N-amido-PEG5-azide is N-Boc protected crosslinker. The hydrophilic PEG spacer increases solubility in aqueous media. the compound can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG5-amine is a Boc protected PEG linker containing an free amino group and5 PEG units. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters. The Boc group can be deprotected under mild acidic conditions to free the amine. Reagent grade, for research purpose.

Bis-PEG3-PFP ester is an amine reactive PEG linker. The two PFP ester moieties can form stable amide bonds and have been found to be very stable because they are less susceptible to undergo hydrolysis. The hydrophilic PEG linker increases the water solubility of the compound in aqueous envionments. Longer PEG chains tend to have enhanced water solubility properties compared to shorter PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
