Colloidal Au nanoparticle-based “turn on” fluorescence imaging for in-gel protein detection†
Abstract
Colloidal Au nanoparticles were first applied for “turn on” fluorescence direct imaging of in-gel proteins after polyacrylamide gel electrophoresis (PAGE). It was successfully used for detecting human proteins after 1-D and 2-D PAGE, providing higher resolution and sensitivity than traditional CBB-R250 imaging.
