PEGylation Products

Profacgen offers a large selection of functionalized PEG products with high purity to fit the diverse needs of our customers. Our current mono-functional PEG products, including amine-reactive PEGs, carboxyl-reactive PEGs and thiol-reactive PEGs, utilize simple but reliable chemistry to deliver highly efficient PEGylation of your target proteins. When PEGylation and crosslinking are needed at the same time, you can easily choose one of our homo/hetero-bifunctional PEGs. Upon request, our experienced chemists are ready to help design and synthesize customized PEG products to meet the specific requirements from our customers.

Our most popular PEG products are summarized below. For additional information or custom synthesis, please contact usor call 1-631-448-8149.
