FOCALCHECK DOUBLEGREE 1 KIT，F36905，Invitrogen

The 6.0 µm FocalCheck™ DoubleGreen Fluorescent Microspheres are designed to test spectral separation on the Zeiss META system and other spectral imaging systems. These microspheres are stained with two different fluorescent dyes that appear similar in color by eye but are sufficiently different to be resolved by linear-unmixing techniques. When linear-unmixing data-processing algorithms are applied, the dyes are shown to be spectrally distinct and spatially separated - one appears only with in the outer ring and the other appears throughout the microsphere. The dual-stained microspheres are provided mounted on a microscope slide. The kits also contain two additional slides containing microspheres stained uniformly with each of the individual dyes.
