PEG Derivatives for PROTAC Linker, ADC Linker, LNP Drug Delivery, etc

Hello <<First Name>>, 

Biopharma PEG provides high-purity PROTAC PEG linkers with various active groups to assist with your PROTAC-related projects. PEG linkers are the most common motifs incorporated into PROTAC linker structures. 

  • PEG linker increases the PROTAC water solubility, affecting the cell permeability, thereby improving oral absorption
  • PEG linker can easily tune their length and composition via some chemical methods. Linker length contributes to degradation efficiency.
  • Bi-functionalized PEG motifs enable the rapid and facile assembly of potent degrader structures.
