| 2 Making an image of radiation emitted by radiolabeled samples | 1 Modern way of capturing radiolabel images; uses a europium crystal array which is read by shining a red laser across it in a reproducible pattern (about $70K) |
| 3 An experimental method commonly used with radiolabeling to track the fate of labeled metabolites (2 wds) | |
| 4 This was used in the old method of imaging radiolabeled samples; its silver halide crystal array captured a light image; unirradiated silver halide precipitated away in alkaline solution and was quenched with acid solution |
