N-Mal-N-bis(PEG4-NH-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. These molecules exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- Used in the synthesis of PROTACs
- PEG-based PROTAC linker
- Facilitates selective degradation of target proteins
- Utilizes the intracellular ubiquitin-proteasome system

Aat Bioquest XFD532 PEG4 biotin conjugate, 1mg
The XFD532 PEG4 biotin conjugate incorporates the XFD532 fluorophore, which is structurally identical to Alexa Fluor 532 and efficiently excited at 532 nm. It exhibits strong orange fluorescence and high avidin-binding efficiency, closely resembling native biotin in affinity, rapid association, and non-cooperative binding to avidin and streptavidin tetramers. This conjugate is particularly well suited for the detection and quantification of biotin-binding sites on avidin, streptavidin, or neutravidin. In contrast to Biotin-4-fluorescein, which suffers from poor aqueous solubility, pH-dependent absorbance, and short-wavelength emission, the XFD532 PEG4 biotin conjugate is fully water soluble and maintains pH-independent fluorescence across the range of pH 4–10.
