Reaction of the spin trap 3,5-dibromo-4-nitrosobenzene sulfonate with human biofluids.
Guo R, Davies CA, Nielsen BR, Hamilton L, Symons MC, Winyard PG. Guo R, et al. Biochim Biophys Acta. 2002 Aug 15;1572(1):133-42. doi: 10.1016/s0304-4165(02)00287-8. Biochim Biophys Acta. 2002. PMID: 12204342
This oxidant has been shown to react with DBNBS to give a 3-line electron paramagnetic resonance (EPR) spectrum, previously assigned to the DBNBS radical cation (DBNBS*(+). However, confusion has arisen as to whether this paramagnetic species is indeed DBN …

Direct modification of low density lipoprotein by the spin trap 3,5-dibromo-4-nitrosobenzenesulfonic acid.
Kalyanaraman B, Joseph J, Kondratenko N, Parthasarathy S. Kalyanaraman B, et al. Biochim Biophys Acta. 1992 Jun 26;1126(3):309-13. doi: 10.1016/0005-2760(92)90245-q. Biochim Biophys Acta. 1992. PMID: 1322177
However, when compared with LDL incubated without DBNBS, the DBNBS-incubated LDL showed increased negative charge on agarose gel electrophoresis and was avidly degraded by mouse peritoneal macrophages. Despite the suggestion of biological modification, there was no …

Mass spectral analysis of protein-based radicals using DBNBS. Nonradical adduct formation versus spin trapping.
Filosa A, English AM. Filosa A, et al. J Biol Chem. 2001 Jun 15;276(24):21022-7. doi: 10.1074/jbc.M100644200. Epub 2001 Mar 21. J Biol Chem. 2001. PMID: 11262405 Free article.
Protein-based radicals generated in the reaction of ferricytochrome c (cyt c) with H(2)O(2) were investigated by electrospray mass spectrometry (ESI-MS) using 3,5-dibromo-4-nitrosobenzenesulfonate (DBNBS). Up to four DBNBS-cyt c ad …

The reactions of 3,5-dibromo-4-nitrosobenzenesulfonate and its biological applications.
Ichimori K, Arroyo CM, Prónai L, Fukahori M, Nakazawa H. Ichimori K, et al. Free Radic Res Commun. 1993;19 Suppl 1:S129-39. doi: 10.3109/10715769309056s129. Free Radic Res Commun. 1993. PMID: 8282215
Recently, 5,5-dibromo-4-nitrosobenzenesulfonate (DBNBS) has been applied to detect biological free radicals. However, DBNBS has various non-specific reactions which lead to preplexing results. ...The other two sextets were assigned to C-centered radical adducts. Thu …

Nitrite determination in human plasma and synovial fluid using reactions of nitric oxide with 3, 5-dibromo-4-nitrosobenzenesulphonate (DBNBS).
Nazhat NB, Saadalla-Nazhat RA, Fairburn K, Jones P, Blake DR, Nielsen BR, Symons MC, Winyard PG. Nazhat NB, et al. Biochim Biophys Acta. 1999 Apr 19;1427(2):276-86. doi: 10.1016/s0304-4165(99)00026-4. Biochim Biophys Acta. 1999. PMID: 10216244
This is identical with the spectrum obtained when NO, introduced from the gas phase, reacts with DBNBS. Under certain conditions, an additional signal is observed, attributable to oxidation of DBNBS to the radical cation, DBNBS*+ (a triplet with alphaN=1.32 m …

ESR spin-trapping of a protein-derived tyrosyl radical from the reaction of cytochrome c with hydrogen peroxide.
Barr DP, Gunther MR, Deterding LJ, Tomer KB, Mason RP. Barr DP, et al. J Biol Chem. 1996 Jun 28;271(26):15498-503. doi: 10.1074/jbc.271.26.15498. J Biol Chem. 1996. PMID: 8663160 Free article.
The intensity of the ESR spectrum corresponding to the DBNBS/*cytochrome c radical adduct was greatly enhanced by performing the reaction under anaerobic conditions, which suggested that the spin trap was competing with O2 for reaction with the radical site(s). Nons …

Purity of different preparations of sodium 3,5-dibromo-4-nitrosobenzenesulphonate and their applicability for EPR spin trapping.
Hamilton L, Nielsen BR, Davies CA, Symons MC, Winyard PG. Hamilton L, et al. Free Radic Res. 2003 Jan;37(1):41-9. doi: 10.1080/1071576021000028451. Free Radic Res. 2003. PMID: 12653216
During the preparation of sodium 3,5-dibromo-4-nitrosobenzenesulphonate (DBNBS) of high purity for electron paramagnetic resonance (EPR) spin-trapping purposes, it was found that the material synthesised as part of the present study differed significantly from some commerc …
