Streptavidin - 5nm Gold Conjugate

Streptavidin - 5nm Gold Conjugate for gold nanoparticle labelling

Streptavidin - 5nm Gold Conjugate supports method development where biotinylated antibodies, probes and capture molecules must be detected in Immunoblotting, Light Microscopy and Electron Microscopy. It helps researchers evaluate target fit, assay readout and control strategy before selecting a related label or antibody format.

Scientific fit

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. The small gold label is well suited to dense targets, fine localization work and protocols where steric access can affect signal quality.

Protocol notes

• Supports Immunoblotting, Light Microscopy and Electron Microscopy workflows where Streptavidin signal needs to be interpreted with appropriate controls.
• Useful when a biotinylated antibody, oligonucleotide or ligand should be converted into a nanoparticle-visible signal.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.

Reference AC-5-04-05 in protocols, purchasing notes and internal reagent libraries when matching this product to your chosen assay. This makes the reagent easier to evaluate during assay planning, troubleshooting and method transfer.
