PepSyn: fluorescently labeled peptides

We are interested in synthesizing a peptide on an ABI 433A for use in a
fluorescent quenching assay, and we have a few specific questions:

1. Are there any solubility problems with using cartridges loaded with
FMOC-Abz-OH, FMOC-Tyr(m-NO2)-OH, FMOC-Lys(DABCYL)-OH, or FMOC-Asp(EDANS)
-OH?

2. Are there any problems associated with the unprotected hydroxyl on the
side chain of FMOC-Tyr(m-NO2)-OH?

3. Does the use of any of these compounds in peptides require that the
cleavage conditions be modified?

Thanks for any help.
