Multiple exposures of a prepared slide from the MultiSpeck™ Multispectral Fluorescence Microscopy Standards Kit.

Multiple exposures of a prepared slide from our MultiSpeck™ Multispectral Fluorescence Microscopy Standards Kit (Cat. no. M7901). This kit provides fluorescent MultiSpeck™ microspheres that exhibit three relatively distinct excitation/emission bands — blue, green and red — all in the same particle. Thus, the same microsphere can appear a different color depending on the optical filter set used. This photograph was taken through bandpass optical filter sets appropriate for DAPI, fluorescein and Texas Red® dyes, with the field of view shifted slightly between exposures.
