20-(Bromoacetamido-PEG4-ethylcarbamoyl)heptadecanoic acid is a PEG linker containing Bromoacetamido and carboxylic acid groups. The bromo is a good leaving group for nucleophilic substitution reactions. 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 purpose.

20-(Bromoacetamido-PEG5-ethylcarbamoyl)heptadecanoic acid is a PEG linker containing Bromoacetamido and carboxylic acid groups. The bromo is a good leaving group for nucleophilic substitution reactions. 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 purpose.

HO-PEG-amine HCl salt, MW 2,000 is an HCl salt of a polyPEG linker with terminal amine and hydroxy groups. The compound reacts with an active NHS or PFP ester to form a stable amide linkage. The hydroxyl group can be deprotonated readily for chemical modification. Reagent grade, for research purpose.

Azide-PEG5-c18-t-butyl ester is a PEG linker with a steric acid tail and a terminal azide group. Stearic Acid is a saturated long-chain fatty acid with an 18-carbon backbone. Azido group will react with DBCO, BCN or other Alkyne group through click chemistry. The PEG spacer increases aqueous solubility. Reagent grade, for research purpose.

4-Arm PEG5-Azide is a multiarm PEG linker containing four terminal azides. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose.

N-bis(Azido-PEG8)-N-(PEG8-t-butyl ester) is a 3-arm PEG reagent with a t-butyl ester group and two azide groups. The t-butyl ester group can be deprotected under acidic conditions. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose.

Amine-PEG5-c18-t-butyl ester is comprised of an octadecanedioic acid with a PEG linker and a terminal amine group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with activated NHS esters to form a stable amide bond. Reagent grade, for research purpose.

DSPE-PEG-endo-BCN, MW 2,000 is a click chemistry reagent with a BCN group attached to a polyPEG linker with hydrophobic lipid tails. The BCN group enables copper free click chemitry with azide-tagged molecules. Reagent grade, for research purpose.

N-bis(Amine-PEG8)-N-(PEG8-t-butyl ester) is a 3-arm PEG linker consisting of a t-butyl ester with two amino groups. The amino (NH2) groups are reactive with activated NHS esters or carboxylic acid. The t-butyl group can be deprotected under acidic conditions. Reagent grade, for research purpose.
