In this paper, a simple, rapid and sensitive flow-injection chemiluminescence method has been developed for the determination of metoprolol tartrate, which acts as a kind of sensitizer in the chemiluminescence emission from the redox of SO(3)(2-) with Ce(IV) in acidic

Upon CS2SO4 density-gradient equilibrium centrifugation, 60S subunits of rat liver ribosomes were dissociated to form three bands at the densities of 1.55, 1.40, and 1.30 g/ml. The bands at 1.55 and 1.30 g/ml were shown to contain exclusively RNA or
Characterization of T4 double-stranded RNA by equilibrium centrifugation in Cs2SO4- and alkaline iodide gradients.

Proteoglycan subunits from human articular cartilage were fractionated by caesium sulphate density gradient centrifugation. A single heterogeneous population of molecules was produced whose average density decreased with increasing age of the individual from which they were obtained. At no density
RNA-protein complexes active for transcription and replication of the double-stranded RNA bacteriophage phi 6 have been partially purified from lysates of infected Pseudomonas phaseolicola. Transcribing particles (filled procapsids) contain the three viral dsRNAs and all four procapsid proteins P1, P2
