Biotin-PEG3-C3-NH2 

Biotin-PEG3-C3-NH2 is a PEG-based PROTAC linker, with NH₂ functional group, that can be used in the synthesis of PROTACs^[1].

PROTAC linkers exert function for connecting the two different ligands that make up PROTACs, the two ligands are E3 ubiquitin ligase and the target protein, respectively^[1].
PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins^[1].
PROTAC can significantly attenuate tumor progression in tumor xenografts^[1].
Biotin-PEG3-C3-NH2 (compound 11) (0-2 mM; 3 h) combinded with protein G (compound 6) displays fluorescence under streptavidin probes, Biotin-PEG3-C3-NH2 is a powerful tool for the high-throughput analysis of protein-small molecule interaction and profiling enzyme activities in a microarrays constructed by surface derivatization method^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
