QUALITATIVE AND/OR QUANTITATIVE DETERMINATION OF A PROTEINACEOUS MOLECULE IN A PLURALITY OF SAMPLES

摘要

The present invention relates to the qualitative and/or quantitative determination of a proteinaceous molecule in a plurality of samples by combining a particular labeling and fractionation strategy. In particular, each sample is provided with a dye chosen from a set of dyes, wherein each dye within the set of dyes emits luminescent light at a wavelength that is sufficiently different from the emitted luminescent light of the remaining dyes in the set of dyes to provide a different light signal when excited. Subsequent to labelling the proteinaceous molecule with the fluorescent dye, the samples are combined and fractionated by means of electrophoresis, the labeled proteinaceous molecule having a relative electrophoretic mobility that differs from the electrophoretic mobility of the proteinaceous molecule labeled with another dye within the set of dyes. After capturing separate images of the labeled proteinaceous molecule at different wavelengths, the images are aligned by means of image processing. The present invention further relates to a kit and a set of luminescent dyes for use in qualitatively and/or quantitatively determining a proteinaceous molecule in a plurality of samples by means of electrophoresis.
