Mass spectrometric analysis of cyanogen bromide fragments of integral membrane proteins at the picomole level: application to rhodopsin.

Analytical Biochemistry, 2001
Advances in time-of-flight mass spectrometry allow unit mass resolution of proteins and peptides up to about 6000 Da molecular weight. Identification of larger proteins and study of their posttranslational or experimental modifications by mass analysis ...

On-line production of [11C]cyanogen bromide

Applied Radiation and Isotopes, 1997
Abstract The electrophilic labelling precursor [ 11 C]cyanogen bromide was produced in 95% radiochemical yield (decay-corrected) from hydrogen [ 11 C]cyanide within 3 min from the end of bombardment using a simple and convenient solid-phase on-line procedure. The [ 11 C]cyanogen bromide has been used in the synthesis of a number of labelled compounds

The cyanogen bromide peptides of bovine soluble and insoluble collagens. I. Characterization of peptides from soluble type I collagen by sodium dodecylsulphate polyacrylamide gel electrophoresis.

Connective Tissue Research, 1976
Acid soluble collagen and purified alpha1 and alpha2 chains were prepared from bovine skin and digested with cyanogen bromide. The resultant peptides were separated by electrophoresis on polyacrylamide gels containing sodium dodecylsulphate.

Cyanogen Bromide Promoted Thiol Dimerization

Synthetic Communications, 1973
Abstract The synthesis of alkyl thiocyanates by the reaction of thiols with cyanogen chloride has been known,1 although it is generally supersede by the more convenient displacement of alkyl halides with alkali thio-cyanates.2 We wish to describe the behavior of sodium thiolates toward cyanogen bromide.

The reaction of monoethanolamine with cyanogen bromide

Chemistry of Heterocyclic Compounds, 1972
The reaction of monoethanolamine with cyanogen bromide has been studied. 2-Imino-1,3-oxazolidine has been obtained and its structure has been proved. It has been confirmed that the reaction of cyanamide or calcium cyanamide with organic oxides and their chlorohydrins forms, in the first stage, hydroxyalkyl derivatives of cyanamide which cyclize with ...

[11] Cyanogen bromide-based assay of thiamin

1997
Publisher Summary This chapter describes the thiochrome method used to develop a low-cost thiamin assay sufficiently sensitive for pediatric application in both whole blood and cerebral spinal fluid, and the normative ranges for those biological fluids. It presents reagents used and procedure employed for sample preparation.

Threshold photoelectron spectroscopy of cyanogen bromide

Chemical Physics Letters, 2004
Abstract A high-resolution (2–15 meV) threshold photoelectron (TPE) spectroscopic study of BrCN was performed using synchrotron radiation and a penetrating-field electron spectrometer over the outer valence ionization region of the molecule. Significant differences were found between the TPE spectrum and the published high-resolution (∼6 meV) HeI ...

Monoclonal antibodies to cyanogen bromide fragments of glycophorin A

Molecular Immunology, 1985
Eleven mouse monoclonal antibodies directed against epitopes on CNBr peptides of the major sialoglycoconjugate of the human red blood cell, glycophorin A, have been produced by hybridomas derived from P3-X63-Ag8.653 myeloma cells and spleen cells from BALB/c mice immunized with purified glycophorin.

The force fields of cyanogen halides. III. Cyanogen bromide and cyanogen iodine

Spectrochimica Acta Part A: Molecular Spectroscopy, 1978
Abstract Following work determining the force fields of FCN and ClCN a related treatment for BrCN and ICN leads to the force fields indicated in Table 1 and giving the agreement with experiment shown by Tables 3, 4 and 5 for BrCN and Tables 7 and 8 for ICN. Table 6 gives the agreement of B 0 values for all isotopic molecules with r e values for

Immunochemical characterization of cyanogen bromide degradation products of M and N blood-group glycopeptides.

European Journal of Biochemistry, 1978
The major glycopeptides purified from the tryptic digests of M and N blood-group glycoproteins were degraded with cyanogen bromide into two fragments. The chemical composition and serological activities of the fragments obtained were determined.
