Molarity Calculator

3-Aminopropyltriethoxysilane (APTES) acts as a strong glue to immobilize biomolecules such as antibodies and enzymes to silicon and silicon derivatives such as silicon nitride (Si3N4 )) on. 3-Aminopropyltriethoxysilane also acts as a spacer, providing biomolecules with more spatial freedom during immobilization for higher specific activity. 3-Aminopropyltriethoxysilane can form a more stable, sensitive, and highly biocompatible bioanalytical platform by immobilizing biomolecules onto some solid materials, electrode materials, nanomaterials, and nanocomposites.

Description

3-Aminopropyltriethoxysilane (APTES) acts as a strong glue to immobilize biomolecules such as antibodies and enzymes to silicon and silicon derivatives such as silicon nitride (Si3N4 )) on. 3-Aminopropyltriethoxysilane also acts as a spacer, providing biomolecules with more spatial freedom during immobilization for higher specific activity. 3-Aminopropyltriethoxysilane can form a more stable, sensitive, and highly biocompatible bioanalytical platform by immobilizing biomolecules onto some solid materials, electrode materials, nanomaterials, and nanocomposites[1][2].

In Vitro

3-Aminopropyltriethoxysilane is unstable in aqueous solution (hydrolytically unstable), and its ethoxy group is easily hydrolyzed into ethanol and trienol group[2].
3-Aminopropyltriethoxysilane. At neutral pH, the half-lives of APTES are 56 h (10°C) and 8.4 h (24°C), respectively[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
