PEG & Diagnosis Solutions

PEG and Diagnosis Solutions

The properties of PEG have been explored in diagnostics in which it has found its role in the delivery of diagnostic probes for magnetic resonance and radiological techniques. Diagnostic agents are usually given in conjugation with macromolecules such as polymers, antibodies, and recognition proteins, or as targeted nanocarrier systems to provide targeted delivery and accumulation. Incorporation of PEG in such systems has shown to further increase their efficiency through site-selective biodistribution. BOC Sciences is a leading provider of comprehensive, high-quality PEG and custom PEG services. We offer a variety of PEG conjugations as well as other PEG solutions. We hope to collaborate with you to explore new frontiers in the biological sciences and accelerate your discoveries.

What Can PEG Offer for Diagnosis?

Currently, research and development efforts on new applications of PEG and its derivatives are mainly focused on drug delivery and targeted diagnostics. Important parameters affecting the biological activity of PEGylated drugs include the length of the PEG chain, the PEGylation site, the linker chemistry, and the temperature chosen for the PEGylation reaction. For example, heat treatment can increase the bioactivity of C-terminal PEGylated staphylokinase, while the pentyl linker of 20 kDa PEG significantly increases the bioactivity of staphylokinase. Furthermore, PEGylation of proteins is largely influenced by the solvents used in the PEGylation process. Peng et al. found that compared with PEGylation in aqueous phase, organic solvents such as DMSO increased the degree of PEGylation, minimized PEG hydrolysis, and decreased the PEGylation time of hydrophobic proteins. Selection of organic solvents for hydrophobic proteins has the potential to reduce reagent costs and reaction times, and these parameters are important for industrial-scale PEGylation processes.
