Surface Plasom Resonance Flashcards
What is measured?
The angle or reelection upon ligand binding to give information on binding
What are the advantages of SPR?
Easy, quick, quantitative, label free, highly sensitive
What are the disadvantages of SPR?
Requires expensive equipment, requires either the ligand or receptor to be bound.
How is SPR set up?
A light source is set to shine through a prism which is sat on a thin metal layer, eg. Gold, which has the bound receptor on the underside of it, the ligand flow through a channel allowing binding to occur. Upon binding the angle at which the light reflects of the metal surface varies and is detected by a detector.
What is SPR?
A quantitative surface sensitive optical detection methods.
