Streptavidin - 100nm Gold NanoUrchins

Streptavidin - 100nm Gold NanoUrchins for NanoUrchin-based assays

Streptavidin - 100nm Gold NanoUrchins supports method development where biotinylated antibodies, probes and capture molecules must be detected in 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.

Workflow value

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.

Use-case guidance

• Helps connect Streptavidin recognition to Immunoblotting, Electron Microscopy and Lateral Flow Assay 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.
