Covalent Streptavidin - 50nm Gold Conjugate

Covalent Streptavidin - 50nm Gold Conjugate for gold nanoparticle labelling

Use Covalent Streptavidin - 50nm 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.

Workflow value

The covalent streptavidin format is selected for biotin-based detection workflows where a robust linkage to the gold label is important. The larger gold label can improve visual contrast while still fitting many membrane, blotting and microscopy workflows.

Use-case guidance

• Fits workflows that require clear Covalent 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.
