Protein A - 50nm Gold NanoUrchins

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

Protein A - 50nm Gold NanoUrchins is a gold NanoUrchin conjugate for detecting compatible immunoglobulins through Protein A 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.

Scientific fit

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.

Protocol notes

• 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.
