Chimeric structural isomer fragments as cost-efficient internal standards for amino acid quantification by mass spectrometry.

Amino acid (AA) profiles from body fluids such as blood and urine are clinical indicators for diagnosing metabolic and hepatic diseases. Current quantitative methods, such as liquid chromatography-mass spectrometry (LC-MS) with isotopically labelled internal standards (ISs), are costly and technically demanding. This study proposes a cost-efficient alternative using structural isomers as ISs in a direct liquid infusion (DLI) tandem mass spectrometry (MS/MS) approach. The method leverages chimeric spectra and fragment intensity ratios to quantify AAs, demonstrating high linearity and precision even with a 3D ion trap mass analyser. This approach offers a viable strategy for AA quantification in preventive medicine, particularly for screening metabolic diseases such as phenylketonuria, diabetes, and liver dysfunction.

The RNA chain elongation rate of the lambda late mRNA is unaffected by high levels of ppGpp in the absence of amino acid starvation.

In this study, the effects of high levels of guanosine tetraphosphate (ppGpp) on the decay and RNA chain elongation kinetics of the bacteriophage lambda late transcript in Escherichia coli were examined in the absence of amino acid starvation. The accumulation, mRNA decay kinetics, and RNA chain elongation rate of the lambda late mRNA were determined after heat induction of lambdacI857 lysogens in the presence of high levels of ppGpp induced from a RelAalpha fragment-overproducing plasmid. The accumulation kinetics and elongation rate determinations of the late mRNA were made at long times after induction to allow a new steady state of transcriptional activities under conditions of elevated intracellular levels of ppGpp. The results indicate no prolonged or significant effect on either mRNA decay or the RNA chain elongation rate of the late mRNA as a result of elevated ppGpp levels. Surprisingly, the RNA chain elongation rate determinations indicate an RNA polymerase processivity of approximately 90-100 nucleotides/s for the lambda late transcript despite the presence of high levels of ppGpp. The results are discussed in terms of various models for regulation of stable and messenger RNA synthesis in E. coli.

Microdetermination of proteins by resonance light scattering spectroscopy with bromophenol blue.

Reaction of bromophenol blue with proteins results in an enhanced resonance light scattering at 334 nm. Based on this, a new quantitative determination method for proteins in the aqueous solution is established. This assay is characterized by high sensitivity (0.34-18.7 microg/ml), short reaction time (>2 min), and simplicity (a one-step assay). Due to protein-to-protein variability, this method gave results higher than that of the bromocresol green assay in detection of human serum albumin.
