Protein L - 20nm Gold Conjugate

Protein L - 20nm Gold Conjugate for gold nanoparticle labelling

Protein L - 20nm Gold Conjugate supports method development where antibody light chains through Protein L binding must be detected 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.

Workflow value

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. This compact gold format gives a balance of accessibility and signal, making it useful across immunoblotting and microscopy method development.

Use-case guidance

• Supports Lateral Flow Assay, Immunoblotting and Electron Microscopy workflows where Protein L signal needs to be interpreted with appropriate controls.
• 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.
