Medchemexpress LLC M-PEG15-NHS ester | 00-00-0 | 98.0% | C39H73NO20 | 10MG
m-PEG15-NHS ester is a methoxy-terminated polyethylene glycol (PEG) N-hydroxysuccinimide ester used as a hydrophilic linker in PROTAC synthesis and bioconjugation. It supplies an amine-reactive NHS group for covalent coupling to primary amines and a PEG15 spacer to improve solubility, flexibility, and distance between conjugated moieties.
- Provides an NHS ester for efficient amine coupling.
- Contains a methoxy-terminated PEG15 spacer to increase solubility.
- High purity (98.0%) suitable for research applications.
- Storage recommended at -20°C, sealed and protected from moisture and light.
- Available in multiple package sizes to support different scales of synthesis.

LifeSensors SUMO Protease 1 5000 Units
LifeSensors' industry leading SUMO Protease 1 (Ulp1), a highly active and robust recombinant protease, cleaves SUMO from recombinant fusion proteins. Unlike thrombin, EK, or TEV protease, which recognize short linear sequences, SUMO Protease 1 recognizes the tertiary structure of SUMO. As a result, SUMO Protease 1 will not cleave within the fused protein of interest. 1 unit will cleave >90 ¿g of hSUMO3-GFP in 1 hr at 37C.
