Mal-PEG4-bis-PEG4-propargyl

Mal-PEG4-bis-PEG4-propargyl is an 8-unit polyethylene glycol linker designed for constructing antibody-drug conjugates (ADCs) . Its terminal alkyne group enables efficient, site-specific conjugation to azide-modified payloads via click chemistry, facilitating ADC development for targeted cancer therapy in both in vitro and in vivo research.
