We report on an ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV based on ligand exchange mechanism. Calcein as a fluorescence indicator and Sudan I-IV as model analytes were employed to investigate the analytical feature of this assay platform.

Rôle of a metabolite in allergenicity of Sudan I
Contact Dermatitis, 1986A metabolite of Sudan I (l‐phenylazo‐2—naphthol) was isolated alter in vitro incubation with the supernatant of guinea pig liver homogenate (S·9). The metabolite was found to be 4′‐hydroxy‐l‐phenylazo‐2—naplithol by gas chromatography‐mass spectrormetry (GC‐MS), and proton and carbon‐13 nuclear magnetic resonance (NMR) analyses.

[Synthesis of Sudan I artificial antigen].
Wei sheng yan jiu = Journal of hygiene research, 2010To prepare Sudan I-HS conjugates with the carrier protein for developing a new immune assay for Sudan I.Sudan I was actived by succinic anhydride and converted into Sudan I hemisuccinate (Sudan I-HS) as the hapten, then Sudan I-HS was linked to carrier protein bovine serum albumin (BSA) as immunogen, and ovalbumin (OVA) as coating antigen all by the ...
