The remaining residue was dissolved in 5 mL of methanol/sodium citrate solution
0.1 M (25/75) and collected into a 5 ml graduated tube.
To analyze the size and morphology of AuC18 and AuC20, first we conducted TEM analysis on freshly synthesized samples and on those stored in the citrate solution
for 3 months (Figure 2).
The third experiment ("Experiment 3") was performed after it was determined that the citrate solution
currently being distributed by the manufacturer, and which was used in the first of these experiments, differed from the 2008 NIST solution in that the original solution contained trace amounts of [Sr.sup.+2].
AuNP (41 nm in diameter) solution was also prepared by using the same method except that only 1 mL of the 1% sodium citrate solution
was added to the flask for the reaction with the 0.01% chloroauric acid solution (100 mL).
VT-050SBCS07 [Terumo Venoject[R] glass, containing 0.5 mL of buffered sodium citrate solution
(32 g/L; final concentration, 0.109 mol/L), hereafter called tube 1;
The higher D-dimer concentration in heparin plasma compared with citrate plasma is attributable to the dilution factor introduced by the citrate solution
. Because all reports in the literature are based on the standard citrate solution
, we therefore multiply the results for the heparin samples by a factor of 0.84 (1/1.19) to avoid the need for changes in reference and cutoff values.
Because these two major PT methods have not previously been compared, the aim of this study was to compare the PT results obtained with two Owren reagents as INR units in samples containing 0.129 mol/L (3.8%) citrate solution
and to compare the PT results and clinical significance with the same calibration between one Owren reagent and one Quick reagent as INR units in samples containing 0.129 mol/L (3.8%) and 0.109 mol/L (3.2%) citrate solution
For most PT measurements, 9 parts of blood are collected with 1 part of citrate solution
[0.109 mol/L (3.2%) or 0.129 mol/L (3.8%)].
