Apexbio Technology LLC Sulfo-NHS-Biotin-Kit-10-20-kDa
Sulfo-NHS-Biotin Kit (10-20 kDa) is a widely used reagent in the field of biomedical research particularly in protein labeling and detection studies Originating from the synthesis of sulfosuccinimidyl esters this kit functions by targeting primary amines on proteins and peptides facilitating biotinylation through a stable amide bond Its mechanism of action is based on the formation of a covalent link between biotin and cellular components enhancing detection and purification processes The in vitro activity is typically in the nanomolar to low micromolar range ensuring precise modification without compromising protein function This kit is commonly applied in cell cultures tissue extracts and animal models serving as a crucial tool in drug screening and diagnostic assay development Experimental concentrations typically depend on the specific research design allowing for flexibility and adaptability in various experimental setups

Medchemexpress LLC M-PEG12-NHS ester | 2207596-93-6 | ≥98.0% | C30H55NO16 | 500 MG
m-PEG12-NHS ester is a PEG-based PROTAC linker designed for the synthesis of PROTACs. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins by connecting a ligand for an E3 ubiquitin ligase and a ligand for the target protein via a linker.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits ubiquitin-proteasome system to degrade target proteins
