Streptavidin - 30nm Gold Conjugate

Streptavidin - 30nm Gold Conjugate for gold nanoparticle labelling

Streptavidin - 30nm Gold Conjugate is a gold nanoparticle conjugate for detecting 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.

Where it helps

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. This mid-sized gold particle is a practical choice when both particle visibility and access to the labelled target must be balanced.

Planning the experiment

• Fits workflows that require clear Streptavidin detection and a reagent choice that can be documented consistently.
• 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.
