Streptavidin - 40nm Gold Conjugate

Streptavidin - 40nm Gold Conjugate for gold nanoparticle labelling

Streptavidin - 40nm Gold Conjugate gives assay developers a defined route to detect biotinylated antibodies, probes and capture molecules across 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

• Helps connect Streptavidin recognition to Immunoblotting, Light Microscopy and Electron Microscopy while keeping the experimental purpose clear for protocol planning.
• 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.
