PEGylated proteins show great advantage over non-PEGylated proteins in terms of non-toxicity, low immunogenicity, high solubility and mobility in solution. PEGylation was also found to be able to mask the target protein drugs from the host’s immune system. The established therapeutic value and high flexibility of PEGylation made it a valuable tool in efficient drug development.Profacgen has developed a series of technologies to increase the site-specificity of our PEGylation process. You can choose from the following according to your specific requirements or we can help recommend the best procedure for you!http://www.profacgen.com/pegylation-services.htm
