Covalent Streptavidin - 40nm Gold Conjugate

Covalent Streptavidin - 40nm Gold Conjugate for gold nanoparticle labelling

Use Covalent Streptavidin - 40nm 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.

Scientific fit

The covalent streptavidin format is selected for biotin-based detection workflows where a robust linkage to the gold label is important. This mid-sized gold particle is a practical choice when both particle visibility and access to the labelled target must be balanced.

Protocol notes

• Supports Immunoblotting, Light Microscopy and Electron Microscopy workflows where Covalent 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.
