What biomolecules are fluorescing red at band pass filters at 470/40, 525/50, 545/25, and 605/70?

I'm counting environmental samples stained with DAPI and counting the bacterial to algal ratios by counting the stained bacteria vs the autofluorescence of the chloroplasts. I'm using a Zeiss...

Will flowcytometry using a BD Accuri 6 FCM, be able to discriminate between SYBR-Green, Nile Red, and Chloroplast to count/ID bacteria and algae?

I am going to run a flow cytometry experiment on synthetic communities of microalgae and bacteria. I would like to use a nuclear stain to determine all the biological particles, and gate those to...
