| abstract |
A method for analysing a sample containing a plurality of analytes, comprises labelling the analytes with a detectable label, the label being chosen such that its detectability can be influenced by modifying the conditions of detection; separating the labelled analytes, before or after labelling; and determining the presence of the separated analytes under the modified conditions and also, if desired, the unmodified conditions. Suitable detection apparatus comprises a support (3) for a gel (2), means (5, 6) for detecting one or more analytes in the gel, and means (4) for reducing the temperature of the gel to below ambient temperature, e.g. to no more than 0 °C. |
