Application

A heterobifunctional cross-linking reagent with amine and sulfhydryl reactivity. Typically, coupled initially to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5). Second coupling specific for molecules containing free sulfhydryl by thioether linkage buffered at pH 6.8 (6.5-7.0). Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates. Provides a 7-atom linker.

Silicon-based implantable neural electrode arrays are known to experience failure during long-term recording, partially due to host tissue responses. Surface modification and immobilization of biomolecules may provide a means to improve their biocompatibility and integration within the host brain tissue.

We modified gold arrays with a glutathione (GSH) surface, and investigated high-throughput protein interactions with a spectral surface plasmon resonance (SPR) biosensor. We fabricated the GSH exterior on gold surfaces by successive modification with aminoethanethiol, 4-maleimidobutyric acid N-hydroxysuccinimide ester and

The specific recognition between monoclonal antibody (anti-human prostate-specific antigen, anti-hPSA) and its antigen (human prostate-specific antigen, hPSA) has promising applications in prostate cancer diagnostics and other biosensor applications. However, because of steric constraints associated with interfacial packing and molecular orientations
