M S Garcia et al.
The Analyst, 116(6), 653-656 (1991-06-01)
A kinetic method for the determination of iodide based on its inhibitory effect on the Pd(III) catalysed reaction between ethylenediaminetetraacetic acid (EDTA)-Co(III) and the hypophosphite ion is described. The reaction was followed spectrophotometrically by measuring the decrease in the absorbance
S P Fling et al.
Analytical biochemistry, 155(1), 83-88 (1986-05-15)
Various buffer systems were examined for their ability to resolve and provide molecular weight determinations of proteins and peptides over a wide size range using electrophoresis in sodium dodecyl sulfate-polyacrylamide gels. Sharp bands and high resolution were achieved in the
J Ambler et al.
Clinical chemistry, 26(8), 1221-1223 (1980-07-01)
Two new non-barbiturate buffers have been formulated for serum protein electrophoresis on cellulose acetate membranes. Both buffers give five distrinct fractions and are suitable for all systems, but have been primarily designed to meet the needs of the Gelman "Sepratek"
A Paulus et al.
Electrophoresis, 11(9), 702-708 (1990-09-01)
Polyacrylamide-filled gel columns are used to separate oligonucleotide samples. For homopolymeric standard samples, plots of migration time versus molecular size are presented over a range of 30-160 bases. With 2.5-4% T and 3.3% C gels, good resolution over the examined
Soham Gupta et al.
Frontiers in immunology, 11, 437-437 (2020-04-01)
The hijacking of cellular function through expression of proteins that interfere with the activity of cellular enzymes and regulatory complexes is a common strategy used by viruses to remodel the cell environment in favor of their own replication and spread.
