m-PEG8-thiol
This product is a high-purity methoxy-PEG derivative with a terminal thiol group connected by a PEG8 spacer, specifically designed for selective conjugation with maleimides, gold surfaces, or other thiol-reactive groups.
Key Features and Benefits
-
Methoxy End Group – Provides stability and minimizes non-specific interactions.
-
Thiol Group – Enables site-specific conjugation to maleimides, disulfides, or metal surfaces.
-
PEG8 Spacer – Enhances solubility, flexibility, and reduces steric hindrance in conjugates.
-
High Purity – Suitable for bioconjugation, surface functionalization, and nanotechnology.
Applications
-
Conjugation of proteins, peptides, or antibodies to maleimide-functionalized molecules
-
Immobilization on gold nanoparticles or thiol-reactive surfaces
-
Development of drug delivery systems and biomaterials
-
Surface modification in biosensor and diagnostic platforms
Storage & Handling
-
Storage: Store at –20 °C, dry, and protected from light.
-
Handling: Dissolve in anhydrous solvents (e.g., DMF, DMSO). Avoid oxidation of thiol groups by working under inert atmosphere when possible.
This product provides a stable methoxy end group and a reactive thiol moiety on a PEG8 spacer, specifically enabling efficient bioconjugation, surface immobilization, and nanotechnology applications with improved solubility and reduced steric hindrance.
