Protein G - 40nm Gold Conjugate

Protein G - 40nm Gold Conjugate for gold nanoparticle labelling

Protein G - 40nm Gold Conjugate supports method development where compatible immunoglobulins through Protein G binding must be detected 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

The colloidal gold label provides a permanent, electron-dense and optically visible signal for method development and routine detection workflows. This mid-sized gold particle is a practical choice when both particle visibility and access to the labelled target must be balanced.

Use-case guidance

• Supports Immunoblotting, Light Microscopy and Electron Microscopy workflows where Protein G signal needs to be interpreted with appropriate controls.
• 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.
