Interpretation of the copeptin diagnostic accuracy through these studies is not evident, first, because analysis comparisons are disrupted by the development of high-sensitivity cardiac troponin T and I assays and the availability of three commercial assays for copeptin (LUMItest, Copeptin Kryptor, Copeptin-us Kryptor).
The majority of PGD testing is restricted in the scope of variants assayed or by the availability of extended family members.
The utility of fluorescent-binding assays requires the availability of pure protein for analysis.
A prerequisite for the development of an Infinium SNP assay is the availability of a large number of genome-wide SNPs.
As B. anthracis strains cured from one or both plasmids exist naturally or may be obtained in vitro (3 ), and false-negative results may be encountered with plasmid-specific PCR assays (4 ), the availability of a chromosomal PCR is desirable.
In all cases, the success of the SNP assays depends on the availability of high-quality DNA samples as the starting reagent.
Appropriate interpretation of many techniques in chromatin biology – such as chromatin immunoprecipitation (ChIP) assays, relies on the availability of highly specific antibodies.
The design of a good MRM assay relies on the availability of peptide spectra from previous discovery-phase LC MS/MS studies.
Their widespread utilization in biological assays relies on the availability of synthetic methods yielding nanoparticles with desired characteristics including high solubility in water, adequate morphology, size dispersion, and surface functionalities.
The ease with which the NAN and GUS reporter activities can be quantified, their compatibility under the same assay conditions, and the availability of fluorogenic and histochemical substrates [35], make them ideal partners for measuring stop codon readthrough efficiencies either via transient expression or in stably transformed plants.
