Typhoon storage phosphor imaging

Storage phosphor detection of radioactivity

> 3H, 125I, 14C, 35S, 33P, 32P, 18F, 99mTc, etc.

The proven storage phosphor capabilities

> Limit of Detection (LOD): 2 dpm/mm2 for 14C> Linear Range: 5 orders with <7.5% std. dev.> Uniformity: + 5% over entire scan area

Storage Phosphor - How it worksBaFBr: Eu+2phosphor at ground state

BaFBr - : Eu+3phosphor absorbs x-rays, a, b or g

BaFBr: Eu+2 *excited F-centre absorbs red laser light to enter unstable state

BaFBr: Eu+2phosphor returns to ground stateEmitting Europium luminescence

Different from film exposureFilm- Not quantitative- Only one copy of the data, not

digital - Low dynamic range

Screen- Quantitative- Save time: 1/5 to 1/10

exposure than film- High dynamic range• Use Image Eraser to erase

Image• DO NOT use detergent on it

Induced biological change - what we want to measure

Benefits of Ettan™ DIGE

Reduce number of gels

Reduce hands on time

Reduce amount of sample required

Ensure accurate quantification of differences in protein abundance through the use of an internal standard

Increase the number of real hits*)
