Covalent Streptavidin - 70nm Gold Conjugate

Covalent Streptavidin - 70nm Gold Conjugate for gold nanoparticle labelling

For protocols centered on biotinylated antibodies, probes and capture molecules, Covalent Streptavidin - 70nm Gold Conjugate provides a focused covalent streptavidin 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.

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 large-format gold label emphasizes strong particle visibility; scientists should optimize blocking, flow and wash conditions for the sample matrix.

Practical use in the lab

• Helps connect Covalent 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.
