An extended stability of the DNPH-glucose derivative in spiked plasma samples was verified via the employed HPLC-UV method.
The quality of the extracted samples was verified by polymerase chain reaction (PCR) and gel-electrophoresis after the extractions.
The purity of complex samples was verified using SDS-PAGE stained with Coomassie Brilliant Blue and then concentrated to 8 mg/mL in 20 mmol/L Tris-HCl pH 8.0, 250 mmol/L NaCl, 5 mmol/L DTT for crystallization.
The amorphous nature of the samples was verified at room temperature by X-ray diffraction (XRD) technique using a ARL X'tra (Thermo Scientific) diffractometer equipped with a copper tube.
The incorporation of MPTS into the silica structures was confirmed by 29Si and 13C nuclear magnetic resonance (NMR) and Raman spectroscopy, while the porosity of the samples was verified with nitrogen sorption measurements.
The applicability of the biosorbent-based fiber in the determination of δ-hexachlorocyclohexane, aldrin, heptachlor epoxide, α-endosulfan, endrin and 4,4′-DDD in water samples was verified, with separation/detection by gas chromatography coupled to electron capture detection (GC-ECD).
As a case study of controllable synthesis based on the QSPR model, the new LDH of Mg Al CO3 system with the desired basal spacing 7.6 Å, which was screened out from a list of LDH dataset consisting of 30 different kinds of samples, was verified by our experiment with the relative error equal to 0.93%.
The presence of tumor tissue on the arrayed samples was verified on hematoxylin eosin stained section.
The quality of the samples was verified by hybridization with specific probes to detect viral RNA and viral/endogenous sRNAs.
The absence of DNA from RNA samples was verified by PCR prior to reverse transcription, using rpoB-specific primers.
The extent of methylated DNA enrichment in our MeDIP samples was verified by qPCR for the normally methylated target region of OXT (Figure S1B and Figure S4).
