Medchemexpress LLC Dspe-peg2-mal | 1915739-87-5 | 99.9% | C55H100N3O14P | 10MG
DSPE-PEG2-mal is a PEG-based linker comprising a distearoylphosphatidylethanolamine (DSPE) lipid connected via a short PEG2 spacer to a maleimide functional group. It is intended for thiol-selective conjugation and linker installation in PROTACs, lipidated probes, and general bioconjugation research.
- Contains a maleimide terminus for selective reaction with thiols.
- Features a short PEG2 spacer to enhance solubility and flexibility.
- Includes a DSPE lipid moiety for membrane anchoring and lipidation.
- High reported purity supports reproducible synthesis and analysis.
- Solid, white to off-white form for ease of handling and storage.
- Available in multiple small-scale pack sizes suitable for research use.
Medchemexpress LLC (S,R,S)-AHPC-PEG2-NH2 | 2010159-60-9 | 95.4% | 575.72 g·mol⁻¹ | C28H41N5O6S | 50 MG
(S,R,S)-AHPC-PEG2-NH2 is an E3 ligase VHL ligand-linker conjugate that links an (S,R,S)-configured AHPC VHL ligand to a two-unit polyethylene glycol (PEG2) spacer ending in a primary amine, used as a building block in PROTAC synthesis.
- VHL ligand-linker conjugate for targeted protein degradation research.
- Contains an (S,R,S)-configured AHPC VHL ligand.
- Features a two-unit PEG linker terminating in a primary amine for conjugation.
- Provided as a free base solid, typically white to yellow.
- Available in small research pack sizes suitable for synthesis workflows.
- High reported purity appropriate for medicinal chemistry and probe synthesis.
