Protein L - 90nm Gold Conjugate

Protein L - 90nm Gold Conjugate for gold nanoparticle labelling

Protein L - 90nm Gold Conjugate is a gold nanoparticle conjugate for detecting antibody light chains through Protein L binding in Lateral Flow Assay, Immunoblotting and Electron Microscopy. It helps researchers evaluate target fit, assay readout and control strategy before selecting a related label or antibody format.

Assay context

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. This large-format gold label emphasizes strong particle visibility; scientists should optimize blocking, flow and wash conditions for the sample matrix.

Experimental considerations

• 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.
