Protein G - 50nm Gold NanoUrchins

Protein G - 50nm Gold NanoUrchins for NanoUrchin-based assays

Protein G - 50nm Gold NanoUrchins gives assay developers a defined route to detect compatible immunoglobulins through Protein G 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.

Assay context

Its NanoUrchin morphology supports red-shifted plasmon behavior and enhanced optical response compared with spherical particles of similar core size. This smaller NanoUrchin format is helpful when particle access and optical response both matter in compact assay geometries.

Experimental considerations

• Helps connect Protein G recognition to Immunoblotting, Light Microscopy and Electron Microscopy while keeping the experimental purpose clear for protocol planning.
• 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.
