Covalent Streptavidin - 15nm Gold Conjugate

Covalent Streptavidin - 15nm Gold Conjugate for gold nanoparticle labelling

Covalent Streptavidin - 15nm 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.

How it fits into the workflow

The covalent streptavidin format is selected for biotin-based detection workflows where a robust linkage to the gold label is important. This compact gold format gives a balance of accessibility and signal, making it useful across immunoblotting and microscopy method development.

Practical use in the lab

• 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.
