Methods for the qualitative and quantitative analysis of thiols by means of the fluorogenic reagent 7-diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin are described, with particular reference to the trypanosomatid metabolites glutathionylspermidine (GSH-spermidine) and trypanothione. Second-order rate constants for the derivatization of seven different thiols under

Inositol 1,4,5-trisphosphate receptors (IP(3)R) and ryanodine receptors (RyR) mediate the release of endoplasmic and sarcoplasmic reticulum (ER/SR) Ca(2+) stores and regulate Ca(2+) entry through voltage-dependent or ligand-gated channels of the plasma membrane. A prominent property of ER/SR Ca(2+) channels is

A microfluorometric assay for thiols has been developed using the thiol-specific fluorochrome N-[4-(7-diethylamino-4-methyl-3-coumarinyl)phenyl]maleimide (CPM). The technique may be used to quantitate either cellular or plasma thiols over a range of 0.01 to 3.0 nmol and may be used with as

N-myristoylation is the irreversible attachment of a C(14) fatty acid, myristic acid, to the N-terminal glycine of a protein via formation of an amide bond. This modification is catalyzed by myristoyl-coenzyme A (CoA):protein N-myristoyltransferase (NMT), an enzyme ubiquitous in eukaryotes

This study aimed to compare the functional capacity and gene expression profile of monocyte-derived dendritic cells (MD-DCs) in HLA-B27+ axial spondyloarthritis (SpA) patients and healthy controls. MD-DCs were differentiated with interleukin 4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF) for seven
