DS-30 Matrix Standard Kit (Dye Set D)

A spectral calibration is an algorithm applied to raw data, which converts it into the component 4 or 5 dye data stored in the sample files. A spectral is created for a specific dye set (combination of dyes), array type (4 or 16 capillaries), and array length (36cm or 50cm). It is used to correct for the natural overlap of the fluorescent dyes.

If the peaks in other colors are directly below the peak of interest, the issue could be that the fluorescent dye being used is not part of the selected dye set, the spectral calibration needs to be performed, or the peaks are offscale. Confirm that the dye set selected on the instrument is compatible with the dye being used, run a new spectral calibration if the correct dye set has been selected and, if the signal intensity is too high, decrease sample concentration during PCR or when preparing samples for electrophoresis.

We do not recommend that you switch dyes in the middle of a project. Switching dyes may result in a shift in the allele sizes as dyes differ in their mobility. If dyes are switched in the middle of a project, it will be necessary to identify the size shift for all the markers/targets in the amplicon product range. The size shift will be consistent throughout the project and it is only necessary to make the adjustment once.

A dye set is a combination of dyes that have minimum spectral overlap, which will allow you to multiplex products of similar size using different dyes. Although the size ranges may overlap, the use of a different dye will allow the software to easily distinguish between these products.
