Biological Activity

Bis-NH2-C1-PEG3 is a PEG-based PROTAC linker utilized in the synthesis of proteolysis targeting chimeras (PROTACs). By joining a target protein-binding ligand with an E3 ubiquitin ligase ligand, PEG-based linkers facilitate the recruitment of target proteins to E3 ligase complexes. This promotes target protein polyubiquitination and subsequent degradation via the ubiquitin-proteasome system, modulating downstream cellular signal transduction pathways. [1][2]

Solvent Solubility & Note
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
