Deterioration of storage phosphor screens with use

Abstract More than 1000 laboratories worldwide use phosphorimager systems for radioisotopic gel and blot quantification. This method is extraordinary sensitive and has a wide dynamic range, and it is therefore often preferred to conventional film‐based analysis. We checked the accuracy of our storage phosphor screen by exposing the same 32 P‐labelled blot in different positions on the same screen. The first exposure took place at the top of …
