The specificity of each primer set and size of the amplicon were verified by analysis with an Agilent Bioanalyzer 2100 and further confirmed by melt curve analysis.
Primer specificity and the size of PCR products were validated by examining melting curves and migration of bands in agarose electrophoresis with ethidium bromide.
While CD8 cells are thought to play an important role in the control hepatitis C infection, low frequencies of virus-specific cells and high numbers of potential determinants have made it challenging to obtain direct and comprehensive data regarding fine specificity and clonal size of the CD8 cells involved.
The specificity and the size of the PCR products were tested by adding a melt curve at the end of the amplifications and by running it on a 2% agarose gel.
Thus, not only can the paracellular barrier discriminate between charged and uncharged solutes, but it may also exhibit an even higher level of specificity distinguishing charge and ionic radius and size of the hydrate shell.
These studies will address key questions about sensitivity, specificity, the size of tumors that can be accurately detected, the mechanisms underlying the observed changes in volatile profiles, the ability to generalize among different types of lung cancers, and the impact of current or former smoking.
Both frequency dependence, a measure of the strength of niche specificity, and colony size, a correlated trait without direct benefits and cost, indicated that ecological diversity within microcosms evolved over the course of the selection experiment.
Considering this tissue specificity and the sample size of our RA cohort, validation of these in vitro assays should be done in cohorts with both RA and other autoimmune disorders.
However, there is great variation among these methods in terms of labeling specificity, velocity, stability, size of the tag, toxicity and versatility to probe structure and cell type and no single method yet succeeds in all these respects.
We transformed the numbers of true positive, false positive, false negative, and true negative based on the provided indices of sensitivity, specificity, and sample size values for statistical calculation.
