In-gel s-pyridylethylation of gel-resolved proteins: whole gel method.

CSH protocols

Simpson RJ.
PMID: 21356843
CSH Protoc. 2008 Jun 01;2008:pdb.prot4604. doi: 10.1101/pdb.prot4604.

INTRODUCTIONThis protocol describes a method for performing reduction and S-alkylation of Coomassie-blue-stained proteins within an intact gel. Reduction is performed with dithiothreitol, and alkylation with 4-vinylpyridine. (Treatment of free cysteines with 4-vinylpyridine yields the S-β-(4-pyridylethyl) cysteinyl derivative.) S-β-(4-pyridylethyl) cysteine-containing...

Application of a coupled reducing system to Edman sequencing.

Addition of low levels of solid tris-(2-carboxyethyl)-phosphine hydrochloride to Applied Biosystems' R4A (2 mM) and R5 (0.17 mM) resulted in a coupled, phosphinedithiothreitol reducing system. Coupling the two reductants eliminated or greatly decreased interference from the oxidation product of...

PMID: 18970049
Talanta. 2005 Apr 30;66(3):755-61. doi: 10.1016/j.talanta.2004.12.038. Epub 2005 Jan 18.

High performance capillary electrophoresis (HPCE) was developed for quantitative determination of 18 phenylthiohydantoin (PTH)-amino acids. The influence of electrolyte concentration, pH, organic modifier and applied voltage on HPCE performance was investigated. The HPCE separation of a PTH-amino acids mixture...

Miniaturized protein microsequencer with PTH amino acid identification by capillary electrophoresis I. An argon pressurized delivery system for adsorptive and covalent sequencing.

Talanta. 1997 Mar;44(3):383-99. doi: 10.1016/s0039-9140(96)02077-2.

The design of a simple, highly miniaturized instrument for manual microsequence analysis of proteins and peptides is described. The reaction chamber is made of fused silica capillary tubing with all reagents and solvents necessary for coupling and cleavage delivered...

In-gel s-pyridylethylation of gel-resolved proteins: individual spot method.

CSH protocols

PMID: 21356844
CSH Protoc. 2008 Jun 01;2008:pdb.prot4605. doi: 10.1101/pdb.prot4605.

INTRODUCTIONThis protocol describes a method for performing reduction and S-alkylation of Coomassie-blue-stained proteins within individually excised, stained protein spots or bands. Reduction is performed with dithiothreitol, and alkylation with 4-vinylpyridine. (Treatment of free cysteines with 4-vinylpyridine yields the S-β-(4-pyridylethyl)...

Absolute configuration, stability, and interconversion of 6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine valine adducts and their phenylthiohydantoin derivatives.

Jiang X, Wang S, Zhao Y, Xia Q, Cai L, Sun X, Fu PP.
PMID: 28911388
J Food Drug Anal. 2015 Jun;23(2):318-326. doi: 10.1016/j.jfda.2015.01.004. Epub 2015 Feb 18.

Pyrrolizidine alkaloid-containing plants are widespread in the world and probably the most common poisonous plants affecting livestock, wildlife, and humans. Pyrrolizidine alkaloids require metabolic activation to form dehydropyrrolizidine alkaloids that bind to cellular proteins and DNA leading to hepatotoxicity,...
