PEG

Biotin-PEG12-TCO is a biotin PEG reagent with a terminal TCO group. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. TCO enables fast click chemistry with tetrazine under mild conditions.

Palmitic acid-PEG2-acid is a saturated long-chain fatty acid with a 16-carbon backbone and a PEG linker connected to a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.

Palmitamide-PEG2-amide-PEG2-acid is a saturated long-chain fatty acid with a 16-carbon backbone and PEG linker containing a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond.

Palmitamide-PEG2-amide-PEG2-NHS ester is a saturated long-chain fatty acid with a 16-carbon backbone and a PEG linker containing a terminal NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

PEG-bis-CH2CO2H, MW 3,400 is a homobifunctional PEG polymer containing terminal carboxylic acid moieties. The carboxylic acid can react with primary amines to form a stable amide bond.

PEG-bis-CH2CO2H, MW 10,000 is a homobifunctional PEG polymer containing terminal carboxylic acid moieties. The carboxylic acid can react with primary amines to form a stable amide bond.

PEG-bis-CH2CO2H, MW 20,000 is a homobifunctional PEG polymer containing terminal carboxylic acid moieties. The carboxylic acid can react with primary amines to form a stable amide bond.

Palmitamide-PEG4-amine TFA salt is a PEG linker with a palmitic acid (C16:0) tail and a terminal amine group. Palmitic acid is useful for building lipid compounds. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc.

m-PEG-Succinimidyl Glutarate, MW 2,000 is a polyPEG linker containing an NHS glutarate ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.
