Description

Colloidal gold is an electron-dense, non-fading marker useful as a probe in electron microscopy, light microscopy and immunoblotting. It requires no additional processing for detection, but in some applications the signal can be enhanced by reaction with silver. It can be complexed with biomolecules by strong, non-covalent interactions. Particles less than 15 nm are most useful in transmission electron microscopy and for applications where access to the probe may be hindered by larger particles.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
