The 16 marble samples used for reference purposes in the present work were taken directly from their respective quarries with the aid of archaeologists.
A total of ten human genomic DNA samples from NIST SRM 2391b (components 1, 3, 4, 5, 7, 8, 9, 10), AmpFℓSTR® Control DNA 007 (Applied Biosystems), and a highly characterized human DNA sample of male origin from NIST (N4124) were used for human reference samples.
'M92-220' wild-type background was used for the reference sample.
After using standard procedures to label genomic DNA that included cyanine 5'-dUTP for test samples and cyanine 3'-dUTP for reference samples, we used an Amicon Ultra-0.5, Ultracel-30 Membrane system (30 kDa; No. UFC5030BK; Millipore, Billerica, MA, USA) to purify the labeled DNA fragments.
A fit to the peak area permits us to determine the relative concentrations of Cu and Se without the need for reference samples, by making use of well-established scattering cross sections.
The proposed method involving PLD and ion implantation seems adequate to produce W-O films load by He that may be used as reference samples for fusion investigations.
Its design guidance is based on the need for a low operational cost and reliable sampler to provide daily aerosol monitoring samples that can be used as reference samples for radiological studies.
DNA samples with known genotypes were used as reference samples for HRM analysis of the two polymorphisms.
Another approach to overcome this difficulty is to use computational approaches, such as the FaST-LMM-EWASher method [ 96] or the RefFreeEWAS method [ 97], which adjust for cell composition without the use of reference samples.
The LBD1-CT proteins were used as the reference samples for calibration of the ELISA.
