Mal-PEG3-NH2 TFA is a linear, heterobifunctional polyethylene glycol (PEG) crosslinker supplied as the trifluoroacetic acid (TFA) salt. It contains a maleimide at one end and a primary amine at the other, enabling thiol-to-amine conjugation and use as a non-cleavable linker in PROTAC and bioconjugation workflows. For research use only.
- Provides maleimide and primary amine reactive groups for orthogonal conjugation.
- PEG3 spacer improves aqueous solubility and reduces steric hindrance.
- TFA salt form enhances stability and handling compared with the free base.
- Non-cleavable linker suitable for stable conjugates and PROTAC constructs.
- High purity (>99%) for consistent conjugation performance.
