Streptavidin - 70nm Gold Conjugate

Streptavidin - 70nm Gold Conjugate for gold nanoparticle labelling

Use Streptavidin - 70nm Gold Conjugate when your workflow needs reliable detection of biotinylated antibodies, probes and capture molecules 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.

Workflow value

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. This large-format gold label emphasizes strong particle visibility; scientists should optimize blocking, flow and wash conditions for the sample matrix.

Use-case guidance

• 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.
