RNA interference (RNAi) technology provides a powerful, yet selective, molecular tool to reduce the expression of genes in eukaryotic cells. Despite the success associated with the effective use of siRNA duplexes for gene silencing, there is a need t

RATIONALE Synthetic polymers of molecular masses up to a few kDa can be analyzed without the use of any matrix by direct laser desorption/ionization mass spectrometry (LDI-MS). In this technique, the surface of the sample plate plays a crucial role,

Diastereoisomers of diethyl 5-substituted (2-thioxo-imidazolidin-4-yl)phosphonates, which can be regarded as protected diethyl 1,2-diaminoalkylphosphonates, have been analyzed by electron ionization mass spectrometry. Significant differences in the f

The methyltransferase that forms m5C967 in Escherichia coli small subunit ribosomal RNA has been purified, cloned, and characterized. The gene was identified from the N-terminal sequence of the purified enzyme. The gene is a fusion of two open readin
