m-PEG45-SSG is a PEG linker incorporating Sodium Starch Glycolate (SSG), the sodium salt of cross-linked carboxymethyl starch. SSG is modified for increased hydrophilicity through substitution and reduced solubility via cross-linking. The PEG45 linker elevates solubility in aqueous media. Reagent grade, for research purpose.

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.
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.
