Protein A - 90nm Gold NanoUrchins

Protein A - 90nm Gold NanoUrchins for NanoUrchin-based assays

Protein A - 90nm Gold NanoUrchins gives assay developers a defined route to detect compatible immunoglobulins through Protein A binding across 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.

Where it helps

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.

Planning the experiment

• Helps connect Protein A recognition to Immunoblotting, Light Microscopy and Electron Microscopy while keeping the experimental purpose clear for protocol planning.
• Useful when the primary antibody class is compatible with Protein A binding and a species-independent detection strategy is desired.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
