Protein A - 70nm Gold Conjugate

Protein A - 70nm Gold Conjugate for gold nanoparticle labelling

Protein A - 70nm Gold Conjugate supports method development where compatible immunoglobulins through Protein A 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.

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 large-format gold label emphasizes strong particle visibility; scientists should optimize blocking, flow and wash conditions for the sample matrix.

Practical use in the lab

• Helps connect Protein A recognition to Immunoblotting, Light Microscopy and Electron Microscopy while keeping the experimental purpose clear for protocol planning.
• 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.
