Lipids & Polymers

m-PEG45-Glycerol constitutes a lengthy PEG linker where the hydroxyl group of the glycerol enables further derivatization or replacement with other reactive functional groups. The PEG45 chain imparts water-solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG45-Alcohol acts as a PEG linker with a benzyl-protecting group and a primary alcohol. The benzyl protecting group can be removed under acidic conditions. The primary alcohol can react to derivatize the compound further. The hydrophilic PEG45 chain increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromo-PEG5-CH2CO2H serves as a PEG linker containing a bromide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Alcohol-PEG6-Sodium is a PEG linker including a hydroxyl group with a terminal carboxylic acid (as sodium salt form). The free acid form is not stable due to the reaction of OH with the PEG-COOH group to form a polymer. The sodium salt form is stable for storage and shipping. 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. 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.

M-PEG62 Alcohol represents a lengthy PEG linker containing a terminal hydroxyl that can be derivatized further for conjugation. The PEG62 chain greatly bolsters the solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG2-Mal serves as a PEG linker comprised of two terminal maleimide groups. The hydrophilic PEG spacer increases solubility in aqueous media. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of the biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

AEEA-AEEA is a non-cleavable linker used in synthesizing antibody-drug conjugates (ADCs) and alkyl chain-based PROTACs for targeted protein degradation. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tos-C16-t-butyl ester contains a t-butyl ester that can be deprotected under acidic conditions and a tosyl group. Tosylates are good leaving groups that are easily displaced by nucleophiles. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

A symmetric polar lipid featuring a two unsaturated oleic acid tails and an azide functional group directly attached to the core. This compound may be used for click chemistry, bioconjugation, and surface modification applications, or as a useful synthetic scaffold for novel lipids. Reagent grade, for research purpose.
