UV excitable dyes

What about Quantum Dots? They have them conjugated to SA as well as to
other secondary antibodies. They also have a kit for conjugating your
own primary antibody (although it isn't cheap). May give you better
options than those you mentioned. The problem with a lot of the other UV
excitable dyes is that there is a lot of autofluorescence in the same
emission range which makes them difficult to use unless you have very
highly expressed epitopes. The Qdots are available for longer wavelength
