(S,R,S)-AHPC-PEG4-NH2 is a VHL E3 ligase ligand-linker conjugate used as a building block in proteolysis-targeting chimera (PROTAC) synthesis. It couples an (S,R,S)-AHPC-derived VHL ligand to a four-unit polyethylene glycol (PEG4) linker terminating in a primary amine, providing a conjugation handle for attachment to target ligands.
- VHL E3 ligase ligand-linker conjugate for PROTAC assembly
- PEG4 linker with terminal primary amine for straightforward conjugation
- Molecular weight 663.83 g/mol
- Typical purity 95.6%; select batches up to 99.51%
- Highly soluble in DMSO (170 mg/mL); ultrasonic agitation recommended
- Powder storage: -20°C (3 years) or 4°C (2 years); in solvent: -80°C (2 years)

Biotin-PEG4-alkyne is a biotin-labeled polyethylene glycol linker bearing a terminal alkyne group for copper-catalyzed azide-alkyne cycloaddition (CuAAC). Supplied as a high-purity solid, it is intended for bioconjugation workflows, affinity capture and detection, and as a linker in targeted degradation (PROTAC) research.
- Terminal alkyne enables CuAAC click chemistry
- Biotin tag for affinity capture and detection
- PEG4 spacer improves solubility and reduces steric hindrance
- High purity for reproducible conjugation
- Available in small and bulk pack sizes for research needs

Molecular Dimensions 50% V/V PEG SMEAR HIGH (250ML)
PEG is an effective crystallization agent due to its protein-protein interaction promoting properties. The BCS Screen overcomes the impracticality of sampling all PEG varieties that has led to a few variants predominating in the most common screens. PEG Smears are designed primarily for efficient screening of chemical space. It is generally thought that well-defined, single PEG species produce the best diffracting crystals. Thus, optimization might involve identifying the single PEG compound that produces the best crystal for structural studies. MOLECULAR DIMENSIONS INC mfg# MD2-250-260
