Medchemexpress LLC (S,R,S)-AHPC-PEG1-N3 | 2101200-09-1 | 98.8% | 557.67 g/mol | C26H35N7O5S | 50 MG
(S,R,S)-AHPC-PEG1-N3 is a VHL E3 ligase ligand-linker conjugate that incorporates an (S,R,S)-AHPC VHL ligand and a single-unit polyethylene glycol (PEG1) linker terminated with an azide. It is designed as a building block for PROTAC assembly and for click-chemistry conjugations (CuAAC), enabling attachment of functional moieties to VHL ligands.
- Contains an azide functional group for copper-catalyzed azide-alkyne cycloaddition (CuAAC).
- Single-unit PEG linker provides improved solubility and controlled spacing between ligands.
- High purity (>98.7%) and molecular weight 557.67 g/mol for consistent characterization.
- Soluble in DMSO (100 mg/mL); insoluble in water (<0.1 mg/mL).
- Stable as a powder when stored at -20°C (up to 3 years) or 4°C (up to 2 years).

Creative Pegworks mPEG-Silane, MW 550, 5g
mPEG-Silane is a linear monofunctional methoxy PEG with a reactive tri-ethoxy silane group. mPEG-Silane with tri-methoxy is available by custom synthesis. Silane PEGylation is often useful to PEGylate glass and hydroxylated surfaces and particles.
Active Motif Sortag-IT™ 3X DBCO Click Labeling Kit, 3 x 100 µg
Sortag-IT™ Labeling Kits are designed for site-specific labeling of Active Motif's highly specific AbFlex® recombinant antibodies (rAb) via the Sortase tag recognition sequence (LPXTG) that is incorporated into the heavy chains of each AbFlex antibody. Directly conjugate fluorophores, enzymes (HRP, AP), biotin, peptides, DNA, carbohydrates, or other labels to the terminal end of the heavy chain to ensure the antigen binding site remains available for target recognition.
