PEG & Drug Delivery Solutions
With the development of drugs from small molecules to peptides and proteins, to nucleic acid drugs, and finally to living cell therapy, new progress has been made in drug delivery technology. The challenges of various therapies can be well resolved through drug modification and microenvironment regulation. Emerging PEG-based drug delivery systems are the pharmaceutical industry's gold standard for treating diseases such as cancer, hemophilia, pain or diabetes. BOC Sciences has developed a one-stop service platform for drug delivery to support the activation and conjugation of PEG. Depending on the type of PEG-conjugated substrate, we can choose the reactive functional groups for PEG activation to achieve the desired drug delivery efficiency.

What Are the Applications of PEG in Drug Delivery?
Drug delivery technologies can enhance drug target delivery, minimize drug off-target effects and improve patient compliance. As therapeutics evolve from small molecules to nucleic acids, peptides, proteins, and antibodies, drug delivery technologies are also developing to address the new challenges. As a multifunctional conjugation ligand for drugs and drug delivery systems, PEG has been widely used as a solubilizing excipient in drug delivery system formulations. For example, PEGylation proteins can reduce the immunogenicity of proteins and prolong their half-life. PEGylated carbohydrates can be used as materials and carriers for new drugs. PEGylated oligonucleotides can improve solubility, nuclease resistance, and cell membrane permeability. PEGylated biomaterials can reduce thrombus formation and protein and cell adhesion.
