Heterobifunctional Linear PEG derivatives have the following general structure: X-PEG-Y, where X and Y are two different functional or reactive groups. Heterofunctional PEG derivatives are often used as crosslinkers or spacers between two different chemical entities, including PEGylation of proteins and peptides, or nanoparticles' surface modification. The PEG moiety in the heterobifunctional PEG derivatives provides water solubility, biocompatibility, and flexibility. They are particularly suitable for the development of antibody drug conjugates (ADCs). To facilitate follow-up studies, we added fluorophores to heterobifunctional linear PEGs for in vivo tracking. CD Bioparticles offers GMP-grade PEG derivatives and bulk orders through custom synthesis, offering the opportunity to meet customer specific quality requirements.
CD Bioparticles manufactures and supplies amine, biotin, FITC, folic acid, hydroxyl, lipoic acid, maleimide, NHS, rhodamine B, and thiol labeled heterobifunctional linear PEGs. Contact us to find out how fluorescent heterobifunctional linear PEGs can help you in your work.
