PEG

NH-bis(PEG3-Boc) is a PEG molecule containing an amino (NH2) group with two Boc protected amines. Amino group is reactive with carboxylic acids, activated NHS esters, carbonyls. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

NH-bis(PEG2-acid) HCl salt is an anqueous soluble branched compound with a central amino group and two terminal carboxylic acids. The amino group is reactive with activated NHs ester, Carboxylic group can react with primary amino groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG3-acid chloride is a PEG linker containing a terminal carboxylic acid. 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. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azide-PEG3-Sulfone-PEG3-azide is a PEG linker containing two azide groups. The azide group enables Click Chemistry with groups such as alkynes, DBCO and BCN. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG3-Sulfone-PEG3-propargyl is a PEG linker containing two propargyl groups. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG4-Sulfone-PEG4-t-butyl ester is a PEG linker containing a propargyl group and t-butyl protected carboxyl group acid. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The t-butyl protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The protected acid can be deprotected by acidic or basic hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Butyloxycarbonyl-PEG4-Sulfone-PEG4-t-butyl ester is a PEG linker containing two t-butyl protecting groups. The t-butyl protecting groups can be removed under acidic conditions. The sulfone group can be conjugated with thiol groups of proteins. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Me-N-bis(PEG2-OH) is a branched PEG linker with two terminal hydroxyl groups. The hydroxy groups enable further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

NH-bis(PEG2-t-butyl ester) is a PEG linker containing an amino group. The amino groups is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
