The study presents the general method of standardization of estimations of total antioxidant activity (TAA) by extrapolating parameters to zero sample concentration based on a pseudo-first-order kinetics model. To test its suitability, the method was applied to the ABTS cation radical scavenging assay...
Sample Preparation Goes Subzero: Ice Concentration Linked with Extractive Stirrer (ICECLES)Logue, Brian A.Skaggs, ChrisAlluhayb, Abdullah H.LC-GC Europe
The sample was drawn from the flask at a specific time interval, and filtered through a 0.45 μm membrane to measure the concentration of Cr(VI) and Cr(III), as well as pH and oxidation-reduction potential (ORP) of the solution were determined by the UV spectrophotometry and a pH meter...
Mesenchymal cells were isolated from the intestine of WT C57BL/6J mice (n = 2). The cells were diluted to a concentration of 100 cells/μl and 1 ml aliquots were used as input to the Drop-seq protocol which was performed as described previously42,57with minor modifications. The bead...
Your reported deviation of 0.13% is only valid for particular Sample of a particular Concentration, but does not tell how good your calibration is over the useful range. (But if all your errors lay only in such a close range, then it will by quite good for GC.) ...
One aliquot with a volume of 0.4ml was diluted in different concentration ratios (1:2, 1:3, and 1:5) as per standard. The results obtained from the diluted samples were adjusted using dilution correction factors before conducting data analysis. All diluted plasma samples were tested within ...
Here, E–I ratio is postulated to be related to the CCO concentration that can be measured non-invasively using broadband (490–900 nm) spectroscopy in humans19,23, as well as in the intact cells and tissues in-vitro24,25 using a proposed 'Phase Zero' clinical study platform26,27. ...

PLE was dissolved in trichloromethane at a concentration of 4 wt%. The solution (6.4 g) was poured into a polytet- rafluoroethylene (PTFE) petri dish (50-mm diameter) with a flat bottom, and evaporated at room temperature for 3 h. The obtained film was dried in vacuo (<0....
This concentration of zeros is referred to as zero inflation. Inflation is assumed to occur in the lowest value to ensure that shifting the levels of the ordinal response variable by a constant will not affect the estimated parameters in the model. This is common in ordered probit models; see...
