Streptavidin - 90nm Gold NanoUrchins

Streptavidin - 90nm Gold NanoUrchins for NanoUrchin-based assays

For protocols centered on biotinylated antibodies, probes and capture molecules, Streptavidin - 90nm Gold NanoUrchins provides a focused gold NanoUrchin conjugate for Immunoblotting, Electron Microscopy and Lateral Flow Assay. It helps researchers evaluate target fit, assay readout and control strategy before selecting a related label or antibody format.

Assay context

Its NanoUrchin morphology supports red-shifted plasmon behavior and enhanced optical response compared with spherical particles of similar core size. This larger NanoUrchin option emphasizes strong optical contrast and particle visibility for readouts where signal intensity is a priority.

Experimental considerations

• Supports Immunoblotting, Electron Microscopy and Lateral Flow Assay workflows where 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.
