Azido-PEG3-maleimide is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azido-PEG3-maleimide is also a cleavable 3 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[2].
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. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker[2].

Detection of proteolytic activity by covalent tethering of fluorogenic substrates in zymogram gels
Biotechniques 2018 May;64(5):203-210.PMID:29793363DOI:10.2144/btn-2018-0005
Current zymographic techniques detect only a subset of known proteases due to the limited number of native proteins that have been optimized for incorporation into polyacrylamide gels. To address this limitation, we have developed a technique to covalently incorporate fluorescently labeled, protease-sensitive peptides using an Azido-PEG3-maleimide crosslinker. Peptides incorporated into gels enabled measurement of MMP-2, -9, -14, and bacterial collagenase. Sensitivity analysis demonstrated that use of peptide functionalized gels could surpass detection limits of current techniques. Finally, electrophoresis of conditioned media from cultured cells resulted in the appearance of several proteolytic bands, some of which were undetectable by gelatin zymography. Taken together, these results demonstrate that covalent incorporation of fluorescent substrates can greatly expand the library of detectable proteases using zymographic techniques.
