Medchemexpress LLC DSPE-PEG2000-Maleimide | 99.6% | 50 MG
DSPE-PEG2000-Maleimide is a phospholipid-PEG conjugate. It utilizes the amphiphilicity of DSPE to insert into the lipid bilayer of liposomes or nanoparticles. This product covalently couples to the sulfhydryl (-SH) of ligands (such as antibodies, peptides, or proteins) via thiol-maleimide click chemistry, which provides targeting capabilities to the particles. It can be used in research related to breast cancer, lymphoma, and inherited retinal degeneration.
- Used to prepare targeted liposomes (TLPD).

DBCO-PEG4-Val-Cit-PAB-MMAE is a cleavable drug-linker conjugate that combines a DBCO-functionalized PEG4-Val-Cit-PAB linker with the cytotoxic payload MMAE. It is supplied as a white to off-white solid for use as a click-chemistry reagent and building block in antibody-drug conjugate synthesis; solutions are unstable and should be prepared fresh.
- Suitable for strain-promoted alkyne-azide cycloaddition (SPAAC)
- Val-Cit-PAB motif provides a cathepsin-cleavable linker
- MMAE payload acts as a tubulin polymerization inhibitor
- High purity supplied (99.18%)
- Provided as a solid; store powder at -20°C
