Protein A - 80nm Gold NanoUrchins

Protein A - 80nm Gold NanoUrchins for NanoUrchin-based assays

Protein A - 80nm Gold NanoUrchins supports method development where compatible immunoglobulins through Protein A binding must be detected 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.

Where it helps

Its NanoUrchin morphology supports red-shifted plasmon behavior and enhanced optical response compared with spherical particles of similar core size. This mid-range NanoUrchin size balances visible signal with practical handling in membrane-based and microscopy workflows.

Planning the experiment

• Supports Immunoblotting, Light Microscopy and Electron Microscopy workflows where Protein A signal needs to be interpreted with appropriate controls.
• 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.
