MULTISPECK MULTISPECT 1 KIT，M7901，Invitrogen

The MultiSpeck™ Multispectrual Fluorescence Microscopy Standards Kit provides an external reference for comparing images collected with different optics, on different instruments and in different laboratories, as well as for monitoring routine day-to-day variations in instrumental performance. The kit includes two suspensions of 4.0 um-diameter microspheres. The first suspension is comprised of multispectral fluorescence microspheres that exhibit three relatively distinct excitation and emission bands all in the same particle. The second suspension is comprised of a mixture of 'single-band' microspheres that exhibit the same three excitation/emission bands - red, green and blue (RGB) as the mutispectral microspheres, but in separate particles. Both suspensions in the kit are provided at ready-to-use densities and can be mounted on slides or incorporated into an experimental sample.
