Profacgen uses high-performance computing to analyze large databases of chemical compounds in order to identify possible drug candidates.The two major types of PEG reagents, linear PEG and branched PEG, are both used in marketed drugs. Linear PEG reagents provide for single, low PEG density modification per attachment, whereas conjugation with branched or multi-arm PEG reagents results in high PEG density per modification, which might be advantageous if mono-PEGylation is applied.
