Application of a fluorogenic reagent, ammonium 7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonate for detection of cystine-containing peptides.

abstract：:1. The distribution of ribosomal protein S1 in subcellular fractions of E. coli was determined by radioimmunoassay. It was found that about 70%, 20% and 10% of protein S1 were present in the high salt (1.0 M NH4Cl)-washed ribosomes, the ribosomal wash and the S100 fraction, respectively. 2. Protein S1 was purified fro...
