Covalent Streptavidin - 90nm Gold Conjugate

Covalent Streptavidin - 90nm Gold Conjugate for gold nanoparticle labelling

Covalent Streptavidin - 90nm Gold Conjugate supports method development where biotinylated antibodies, probes and capture molecules must be detected 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 large-format gold label emphasizes strong particle visibility; scientists should optimize blocking, flow and wash conditions for the sample matrix.

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.
