Medchemexpress LLC Rhodamine B PEG2-NH2 | 95.3% | 566.13 | 25 MG
Rhodamine B PEG2-NH2 is a PEG-based PROTAC linker. It is used in the synthesis of PROTACs, which contain two different ligands connected by a linker: one for an E3 ubiquitin ligase and the other for the target protein. These PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins. For research use only.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Facilitates targeted protein degradation

Medchemexpress LLC DSPE-N3 | 2839508-98-2 | 96.4% | 831.11 g/mol | C43H83N4O9P | 50 MG
DSPE-N3 is an azide-functionalized phospholipid used as a click-chemistry reagent for biochemical research. It enables covalent conjugation via azide-alkyne cycloaddition and is commonly used to functionalize liposomes, nanoparticles, and biomolecules for labeling or targeted delivery applications.
- Contains an azide functional group for copper-catalyzed azide-alkyne cycloaddition (CuAAC).
- Compatible with strain-promoted alkyne-azide cycloaddition (SPAAC) for copper-free reactions.
- Suitable for liposome and surface functionalization in biochemical studies.
- Supplied as a white to off-white solid with high purity.
- Soluble in DMSO (12.5 mg/mL) with sonication and heating.
- Recommend sealed storage at 4°C; in solution: -80°C (6 months), -20°C (1 month).
