MEDCHEMEXPRESS LLC M-PEG12-NHS ester | 2207596-93-6 | >=98.0% | C30H55NO16 | 100 MG
m-PEG12-NHS ester is a PEG-based PROTAC linker that plays a crucial role in the synthesis of PROTACs. These molecules are designed with two distinct ligands, one targeting an E3 ubiquitin ligase and the other a target protein. This innovative mechanism enables PROTACs to leverage the intracellular ubiquitin-proteasome system for the selective degradation of specific target proteins, offering a novel approach in drug discovery.
- Utilized in the synthesis of PROTACs
- Features a PEG-based linker
- Facilitates targeted protein degradation
- Leverages the ubiquitin-proteasome system
- Designed for research use

Vector Laboratories Wheat Germ Agglutinin (WGA) Fluorescein-labeled 5 mg
Wheat germ agglutinin (WGA) contains a group of closely related isolectins that bind N-acetylglucosamine (preferentially the dimers and trimers of this sugar) and oligosaccharides containing terminal N-acetylglucosamine or chitobiose, structures common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, cartilage glycosaminoglycans, and glycolipids can also bind WGA. Native WGA also interacts with some glycoproteins via sialic acid residues (see succinylated WGA). This fluorescein-labeled WGA features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 495 nm, emission 515 nm). Supplied as a solution essentially free of unconjugated fluorophores, it is preserved with sodium azide. The recommended inhibiting/eluting sugar is chitin hydrolysate or 500 mM N-acetylglucosamine with salt and/or acid elution.
