Spectral shifts Cy5 upon incorporation into cDNA MCR extracted spectral profiles of Cy5-dCTP (blue trace) and Cy5-cDNA (green trace). Spectra profiles were obtained from MCR analysis of hyperspectral images from two individual spotted arrays manufactured in-house containing spots of only Cy5 bound to dCTP and Cy5 incorporated into cDNA. Spectral traces are normalized for maximum intensity equal to one
