Within 30 minutes of blood withdrawal, samples were centrifugated at 5,000 rounds per minute for 15 minutes.
Twenty stated that upon withdrawal samples would be destroyed, but information that had already been incorporated into research would not be removed.
To examine the effects of IL-2 withdrawal, samples were compared either according to the type of the cell line (primary/immortalised) in a block design or in a paired sample t-test analysis (for this analysis the replicates of the same sample were averaged).
As expected, MdOS inhibited the phosphorylation of HER-2 in SK-OV-3 cells in the MdOS-withdrawal sample similar to that in MdOS-unwithdrawal sample (Fig. 3B, left).
A 10-mL volume of fresh dissolution medium (PBS solution) was added to make up the volume after withdrawal of sample.
Major challenges in BC testing are low rates of true positivity due to antibiotic pretreatment prior to blood withdrawal, suboptimal sample volume, an inadequate number of BC bottles cultured and delays in time to incubation.
Samples were withdrawn at regular intervals, 0 6 h on the 1st day followed by withdrawal of samples at every 24 h for 14 days.
Fluid withdrawal during sampling likely caused some minor convection within the reservoir, which was simulated by increasing the apparent liquid diffusion coefficient.
Directly after withdrawal, the samples were centrifuged (2000 g, +20 °C) for 10 min and the plasma was transferred into Eppendorf tubes and stored at −70 °C until analysis.
While the present arteriovenous shunt method allows the investigator to avoid blood loss where desired, the inclusion of a T-connection for blood withdrawal facilitates sampling for metabolites.
BOD concentration of incubations was not monitored as withdrawal of samples for BOD analysis, volume-wise, would interfere with the assessment of FC decay and therefore dissolved oxygen profile was used to explain possible changes in BOD.
