Amino-PEG8-acid
This product is a high-purity heterobifunctional PEG linker featuring a terminal primary amine and a terminal carboxylic acid group, separated by a PEG8 spacer specifically to improve solubility and flexibility.
Key Features and Benefits
-
Primary Amine Group – Provides a reactive handle for coupling with carboxyls, NHS esters, or other electrophiles.
-
Carboxylic Acid Group – Enables amide bond formation with amines for bioconjugation.
-
PEG8 Spacer – Enhances aqueous solubility, reduces steric hindrance, and increases conformational flexibility.
-
High Purity – Suitable for protein modification, probe design, and drug delivery research.
Applications
-
Crosslinking proteins, peptides, or antibodies
-
Amide coupling for probe, polymer, and nanoparticle functionalization
-
Linker for drug delivery systems and targeted therapeutics
-
Surface modification in biosensors and biomaterials
Storage & Handling
-
Storage: Store at –20 °C, dry, and protected from light.
-
Handling: Dissolve in anhydrous solvents (e.g., DMF, DMSO) or aqueous buffers when appropriate. Avoid repeated freeze–thaw cycles.
