Bis-PEG1-C-PEG1-CH2COOH

Bis-PEG1-C-PEG1-CH2COOH, known as PROTAC Linker 26, is a polyethylene glycol-based bifunctional linker used to construct PROTAC molecules. These compounds facilitate targeted protein degradation, a strategy widely applied in both in vitro biochemical assays and in vivo preclinical research for probing disease pathways and therapeutic development.
