Protein A - 15nm Gold Conjugate

Protein A - 15nm Gold Conjugate for gold nanoparticle labelling

Protein A - 15nm Gold Conjugate gives assay developers a defined route to detect compatible immunoglobulins through Protein A 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.

Where it helps

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.

Planning the experiment

• Fits workflows that require clear Protein A detection and a reagent choice that can be documented consistently.
• 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.
