Antibiotic Identification by High Voltage Electrophoresis Bioautography

Resolution of antibiotic mixtures in serum samples by high-voltage electrophoresis.

The use of high-voltage electrophoresis and bioautography for the separation mixtures of antibiotics received in clinical serum samples is described. The electrophoretic characteristics of 39 antibiotics are given as is the accuracy of the method for quantitating three antibiotics. In screening 189 consecutive serum samples submitted for routine antibiotic assay, undisclosed antibiotics were r...

power system voltage stability enhancement by high side voltage control

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.

BIOAUTOGRAPHY SHOWS ANTIBIOTic PRODUCTION BY SOIL BACTERIAL ISOLATES ANTAGONISTIC TO FUNGAL DRY ROT OF POTATOES

Twenty bacterial antagonists of postharvest dry rot of potatoes (caused by Fusarium sambucinum) were screened for the production of antibiotics by bioautography. Samples of liquid cultures of bacterial strains harvested at three growth times and extracted with three solvents at three pHs were used to directly detect antibiotics inhibitory to F. sambucinum grown on the surface of thin-layer chro...

Studies on PTH-amino acids by high voltage filter paper electrophoresis.

Improved analysis for urinary polyamines by use of high-voltage electrophoresis on paper.

This method for assay of polyamines (putrescine, spermidine, and spermine) in large numbers of urine samples is based on preliminary analyte isolation by use of a Dowex 50W column, separation by high-voltage paper electrophoresis, reaction with ninhydrin to detect the separated amines, and subsequent direct assay with a dual-wave-length thin-layer chromatography scanner by the zigzag scanning m...
