I am searching for a FP and the correspondant antibody which can be distinguished from both GFP and MCherry. I tried EBFP but unfortunately the antibody I am using (from AbCam) recognises also GFP. I would like to use Dsred but I am not quite sure I will be able to distinguish it from MCherry.
You could try using FPs with different tags (e.g. FLAG tag) and use specific antibodies against these tags. I wonder what the setting of your experiment is and why you need to detect FPs with an antibody, nonetheless this might be an option that eliminates cross-reactivity.
You could try the newer completely synthetically designed fluorophores like mScarlet and mNeon. There should be no cross reactivity with them with any GFP or mCherry antibodies.
Check http://evrogen.com/products/basicFPs.shtml and sites of providers of other fluorescent proteins for the spectral properties of different fluorescent proteins.
This page list some other properties to consider in your choice of fluorescent protein besides the spectral range, depending on your application: https://blog.addgene.org/which-fluorescent-protein-should-i-use
