Protein L - 50nm Gold NanoUrchins

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

Use Protein L - 50nm Gold NanoUrchins when your workflow needs reliable detection of antibody light chains through Protein L 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.

Where it helps

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.

Planning the experiment

• Fits workflows that require clear Protein L detection and a reagent choice that can be documented consistently.
• Useful when light-chain binding is preferred, especially for workflows where Fc-dependent recognition is less suitable.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
