The Molecular Dynamics Storage Phosphor Screen 35 x 43 cm captures latent images produced by ionizing radiation.
Upon laser-induced stimulation, light is emitted from the storage phosphor screen in proportion to the amount of radioactivity in the sample. The resulting digital image allows for quantification of subtle signal intensity differences over a wide dynamic range using storage phosphor imaging systems.
Storage phosphor screens are reusable and are not degraded by repeated exposure to laboratory levels of radioactivity. Exposing the screen to ionizing radiation results in latent image formation. The screen is then scanned by lasers, which makes the crystals in the screen release energy as blue light. The blue light is collected and measured to form a quantitative representation of the sample.
General Purpose (GP) and Multipurpose Standard (MS) screens are reliable for a wide variety of applications and can be used with 32P, 125I, 35S, 33P, and 14C. The durable cellulose acetate coating and the phosphor layer formulation make the GP and MS screens well suited for 32P and 125I detection and quantitation. They are the screens of choice for 32P Northerns and Southerns and 125I Western blots and gels.
