Abstract
This article describes data related to a research article entitled “Fluorescent cyanine dyes for the quantification of low amounts of dsDNA” (B. Bruijns, R. Tiggelaar, J. Gardeniers, 2016) [1]. Six cyanine dsDNA dyes - EvaGreen, SYBR Green, PicoGreen, AccuClear, AccuBlue NextGen and YOYO-1 – are investigated and in this article the absorption spectra, as well as excitation and emission spectra, for all six researched cyanine dyes are given, all recorded under exactly identical experimental conditions. The intensity graphs, with the relative fluorescence in the presence of low amounts of dsDNA, are also provided.

1. Data
Cyanine dyes can be used to quantify the amount of dsDNA within a sample. The linearity of fluorescence, as function of DNA amount of six dyes, is obtained by measuring the fluorescence intensity at the optimal excitation and emission maxima.
In Appendix A of Supplementary material a detailed overview is given about the characteristics and spectral behaviour of the researched dyes, such as the absorption, excitation and emission wavelengths at which maxima occur. The wavelengths at which these maxima occur as available in literature are listed in Table 1.1 and the measured dataset of the absorption, emission, excitation and fluorescence intensity graphs are given in Fig. 2.1, Fig. 2.2, Fig. 2.3, Fig. 2.4, Fig. 2.5, Fig. 2.6, Fig. 2.7, Fig. 2.8, Fig. 2.9, Fig. 2.10, Fig. 2.11, Fig. 2.12, Fig. 2.13, Fig. 2.14, Fig. 2.15, Fig. 2.16, Fig. 2.17, Fig. 2.18, Fig. 2.19, Fig. 2.20, Fig. 2.21, Fig. 2.22, Fig. 2.23, Fig. 2.24, Fig. 2.25, Fig. 2.261 (and listed in Table 3 in [1]).

2. Experimental design, materials and methods
The materials and methods used to obtain the dataset of the absorption, excitation, emission and fluorescence intensity graphs are given in [1].
Footnotes
Since fluorescence is measured in relative fluorescence units (RFU), data cannot be directly compared. Therefore, relative intensities are used in most procedures; the data in most of the graphs are normalized. For the absorbance graphs with all the dyes also the background is subtracted (i.e. the lowest value equals 0).
