4-arm PEG Vinylsulfone (4-arm PEG VS), MW 10K is a versatile PEG derivative with four reactive vinylsulfone groups. It efficiently binds free thiol groups in aqueous buffers at pH 6.5 to 8.5, making it ideal for rapid bioconjugation at room temperature.
Key Features:
- Molecular Weight: 10,000 Da (10K)
- Structure: Four PEG arms, each ending in a vinylsulfone group
- Reactivity: Quickly reacts with thiol groups to form stable thioether bonds in pH 6.5-8.5 conditions
- Applications:
- Protein and peptide modification for targeted therapies
- Hydrogel formation in biomaterials
- Bioconjugation in drug delivery systems
- Tissue engineering for regenerative medicine
4-arm PEG VS works fast and efficiently, enabling precise functionalization and modification in biomedical research. Its ability to bind under mild conditions makes it a go-to option for various applications.
