The most widely used method for qualitative and quantitative analysis of carbonyl compounds is the 2,4-dinitrophenylhydrazine method through the formation of 2,4-dinitrophenylhydrazone derivatives. However, this method may cause an analytical error because 2,4-dinitrophenylhydrazones have both E- and Z-stereoisomers. Purified aldehyde-2,4-dinitrophenylhydrazone...

We have previously reported that Major Histocompatibility Complex (MHC) class II can be induced by histone deacetylase inhibitors (HDACi) in the absence of class II transactivator (CIITA). Here we characterized the histone modifications associated with the CIITA-dependent (IFN-gamma induced) and...

MAPK signal transduction pathways are important regulators of stress responses, cellular growth, and differentiation. In Neurospora, the circadian clock controls rhythms in phosphorylation of the p38-like MAPK (OS-2); however, the mechanism for this regulation is not known. We show that...
