4-arm PEG-CH2COOH, MW 2,000 is a 4-arm branched PEG linker with four carboxylic acid groups. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond. Reagent grade, for research use only.

8-arm PEG-acid, MW 10,000 is an 8-arm branched PEG linker with four carboxylic acid groups. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond. Reagent grade, for research use only.

Methyltetrazine-PEG23-amine is an aqueous souluble PEG linker containing a free amine and a methyltetrazine group. Methyl group improves the stability and hydrophilic PEG spacer increases water-solubility. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene), the amine (NH2) group is reactive with carboxylic acid containing molecule in the presence of reagnet such as EDC or HATU. Reagent grade, for research use only.

ACRL-PEG-acid, MW 1,000 is a polyPEG linker containing an acrylate and carboxylic acid groups. The acrylate group enables Michael addition reactions. The hydrophilic polyPEG spacer increases solubility in aqueous media. The carboxylic acid moiety can be used for bioconjugation with amine in the presence of activating agent, such as HATU or EDC. Reagent grade, for research use only.

HO-PLGA-acid (LA/GA 75:25), MW 20,000 is a poly (lactide-co-glycolide) copolymer which can be used to prepare nanomicellar for for sustained release drug delivery. The lactide to glycolide raio is 75% lactide and 25% glycolide. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The carboxylic acid can react with primary amine groups to form a stable amide bond. Reagent grade, for research use only.

MPEG(1K)-pGlu(3K) is a block coploymer comprised of PEG and L-glutamic acid (pGlu). The hydrophilic polyPEG spacer increases solubility in aqueous media. pGlu is soluble in water(alkaline solution), dichloroacetic acid, chloroform, DMF, dioxane, and acetic acid. Reagent grade, for research use only.

MPEG(1K)-pGlu(7.5K) is a block coploymer comprised of PEG and L-glutamic acid (pGlu).
