Protein G - 20nm Gold Conjugate

Protein G - 20nm Gold Conjugate for gold nanoparticle labelling

Protein G - 20nm Gold Conjugate gives assay developers a defined route to detect compatible immunoglobulins through Protein G binding across 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.

How it fits into the workflow

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.

Practical use in the lab

• Fits workflows that require clear Protein G detection and a reagent choice that can be documented consistently.
• Useful when broad immunoglobulin binding through Protein G fits the host species and subclass in your protocol.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
