Protein A - 100nm Gold NanoUrchins

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

Protein A - 100nm 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.

Workflow value

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.

Use-case guidance

• Fits workflows that require clear Protein A detection and a reagent choice that can be documented consistently.
• 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.
