Streptavidin - 50nm Gold Conjugate

Streptavidin - 50nm Gold Conjugate for gold nanoparticle labelling

For protocols centered on biotinylated antibodies, probes and capture molecules, Streptavidin - 50nm Gold Conjugate provides a focused gold nanoparticle conjugate for 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.

Assay context

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. The larger gold label can improve visual contrast while still fitting many membrane, blotting and microscopy workflows.

Experimental considerations

• 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.
