I don't know where the "S-" stands for, but DABITC
(4-dimethylaminoazobenzene-4'isothiocyanate) is used as an orange colored dye
in manual protein sequencing (Edman degradation). It binds to terminal NH2's 
(including the secondary Lys NH2) in proteins. I don't know if it's fluorescent
Sigma sells this for HFL 43,50 per 100 mg in The Netherlands, so its about
twice as cheap as the Cambridge Bioscience equivalent, and it works fine!
