Dark brown serum and plasma samples

Serum and plasma samples for ACS:systems cardiac markers.

To The Editor: The ACS:180 immunoassay system (Bayer Diagnostics) is an automated random analyzer that uses acridinium ester-based chemiluminescence detection. The architecture of the cardiac marker assays is a heterologous sandwich format, using monoclonal anti-marker antibody immobilized onto paramagnetic particles (capture) and polyclonal goat anti-human myoglobin, creatine kinase MB isoenzy...

Structuring Racist Ideologies in Stephen Crane’s “A Dark Brown Dog”: A Critical Discourse Analysis

This paper deals with the study of how racist ideologies are constructed in Crane’s “A Dark Brown Dog” using the CDA framework. Benefitting from the approaching between literature and linguistics, it focuses on the linguistic examination of the (re)construction of whiteness and blackness based on the assumption that racism is: a social, a discursive, and an ideological construct. This tri-dimen...

Effect of Repeated Freezing and Thawing on Biomarker Stability in Plasma and Serum Samples

OBJECTIVES The stability of circulating proteins can be affected by repeated freezing and thawing. The aim of our study was to identify the effect of repeated freezing and thawing on the plasma and serum concentrations of eight proteins [interferon-γ, interleukin (IL)-8, IL-15, IL-17A, matrix metalloproteinase (MMP)-7, tumor necrosis factor-α, vascular endothelial growth factor (VEGF), and VEGF...

Targeted Metabolomics Identifies Reliable and Stable Metabolites in Human Serum and Plasma Samples

BACKGROUND Information regarding the variability of metabolite levels over time in an individual is required to estimate the reproducibility of metabolite measurements. In intervention studies, it is critical to appropriately judge changes that are elicited by any kind of intervention. The pre-analytic phase (collection, transport and sample processing) is a particularly important component of ...
