J Hempel et al.
FEBS letters, 194(2), 333-337 (1986-01-06)
A synthetic peptide analog, with one peptide carbonyl group replaced by a methylene bridge, was submitted to structural analysis by Edman degradation. Multiple cleavages were obtained in the first cycle, due to phenylthiocarbamylation of the internal secondary amine as well

N-epsilon-lithocholyl lysine (NELL) is a component of tissue-bound lithocholic acid (TBL). The isolation of NELL from native protein sources was simulated by hydrolysis of lithocholyl-bovine serum albumin (BSA) (synthesized by coupling lithocholyl-N-hydroxysuccinimide to fatty acid-free BSA) by digestion with a

An easy and highly sensitive method for measuring histamine by HPLC analysis coupled with precolumn derivatization was established. The amino group of histamine was completely colorimetrically labelled with 4-N,N-dimethylamino-azobenzene-4'-isothiocyanate (DABITC) in the presence of sodium bicarbonate at 90 degrees C
P M Fischer et al.
Analytical biochemistry, 177(1), 46-49 (1989-02-15)
A single-column high-performance liquid chromatographic separation of 4-N,N-dimethylaminoazobenzene 4'-thiohydantoin amino acid derivatives, generated during polypeptide sequence analysis by the 4-N,N-dimethylaminoazobenzene 4'-isothiocyanate/phenylisothiocyanate double coupling technique, is described. Recovery of the serine and threonine derivatives was improved by substituting boron trifluoride-diethyl etherate
R Aebersold et al.
Analytical biochemistry, 136(2), 465-469 (1984-02-01)
Proteins and polypeptides are derivatized with dimethylaminoazobenzene isothiocyanate (DABITC) before their separation on sodium dodecyl sulfate-polyacrylamide gels. DABITC-derivatized proteins are detected visually in the picomole range without further staining and destaining procedures. The recovered colored protein can also be used
