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.

Aplicaciones
El oro coloidal es un marcador denso en electrones, sin decoloración útil como sonda en microscopía electrónica, microscopía óptica e inmunotransferencia. No requiere procesamiento adicional para la detección, pero en algunas aplicaciones la señal se puede mejorar por reacción con plata. Puede formar complejos con biomoléculas mediante interacciones fuertes, no covalentes. Las partículas inferiores a 15 nm son más útiles en microscopía electrónica de transmisión y para aplicaciones en las que el acceso a la sonda puede verse obstaculizado por partículas más grandes.

Solubilidad
Completamente miscible en agua. Es soluble en aqua regia, ácido nítrico y ácido clorhídrico.
