Protein A - 50nm Gold Conjugate

Protein A - 50nm Gold Conjugate for gold nanoparticle labelling

Protein A - 50nm Gold Conjugate is a gold nanoparticle conjugate for detecting compatible immunoglobulins through Protein A 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.

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. The larger gold label can improve visual contrast while still fitting many membrane, blotting and microscopy workflows.

Practical use in the lab

• Supports Immunoblotting, Light Microscopy and Electron Microscopy workflows where Protein A signal needs to be interpreted with appropriate controls.
• Useful when the primary antibody class is compatible with Protein A binding and a species-independent detection strategy is desired.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
