Protein G - 100nm Gold NanoUrchins

Protein G - 100nm Gold NanoUrchins for NanoUrchin-based assays

Protein G - 100nm Gold NanoUrchins is a gold NanoUrchin conjugate for detecting compatible immunoglobulins through Protein G binding 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.

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, Light Microscopy and Electron Microscopy workflows where Protein G signal needs to be interpreted with appropriate controls.
• Useful when broad immunoglobulin binding through Protein G fits the host species and subclass in your protocol.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
