I'm optimizing a flow cytometer experiment and one of my three stains is a 7-AAD Live/Dead stain. The other stains in my experiment are staining for CD34+ and CD45+ cells. Is it necessary to include an FMO control for Live/Dead?
The indexes NDWI and MNDWI are use to identify waterbody. Can I use these index to identify wetland also? Thank you for advance.
