Stability of plasma electrolytes in Barricor and PST II tubes under different storage conditions

Stability of plasma electrolytes in Barricor and PST II tubes under different storage conditions

INTRODUCTION Sample stability can be influenced by many different factors; evaporation and leakage from residual cells are the most relevant factors for electrolytes. During the analytical phase, samples are usually kept uncapped at room temperature. Once samples are processed, they are usually stored sealed and refrigerated. Long turnaround time and the possibility of "add-on test" need consid...

miRNA in plasma exosome is stable under different storage conditions.

Exosomes are small membrane-bound vesicles secreted by most cell types. Exosomes contain various functional proteins, mRNAs and microRNAs (miRNAs) that could be used for diagnostic and therapeutic purposes. How we should store the samples before RNA isolation and whether those long term stored samples could be used for circulating RNA investigation because of RNase is unknown. The aim of the st...

Long-term stability of propofol in human plasma and blood in different storage conditions.

Stability of Plasma Polymers Under Various Conditions

In the first part of this paper, stability in the open air and ageing of plasma polymer films is concisely reviewed. Nanocomposite films metal/plasma polymer are shortly discussed. Their ageing is considered. Future work on more complex composites such as Sn or SnO2 /plasma polymer films is outlined.

Evaluation of glucose-6-phosphate dehydrogenase stability in blood samples under different collection and storage conditions.

To the Editor: Fujimoto et al. (1 ) reported that the stability of galactose 1-phosphate in dried blood spots for neonatal screening was adversely affected by humidity and temperature, especially when low-value samples are evaluated. We extend these findings to glucose-6-phosphate dehydrogenase (G-6-PD; EC 1.1.1.49) activity, deficiency of which is by far the most common genetic disease worldwi...
