In such a system, the bilayer separation, precisely adjusted by adding the correct amount of aqueous solvent to the sample [23] [25], is checked by Small Angle X-ray Scattering (SAXS) measurements (Supplementary data figure S1).
For two-dimensional pieces, the camera lens should be placed parallel to the work (in order to reduce distortion and blurriness), aimed at the center of the piece, and the alignment should be checked by a small level on both the camera and the artwork.
This can be checked by centralized SON entities as well as between small cells.
The quality of a library was checked by sequencing a small number of plasmids, which were assembled by phrap and aligned by BLAST to validate the randomness of the library and the proportion of contaminations – including mitochondrial DNA, human fragments and vector sequences.
Quality of mRNA purification was checked by electrophoresis of a small aliquot on 1% agarose and by a reverse transcription test using trace amounts of [α-32P] dCTP.
When some of the Eskimos themselves were checked by analysis of fat samples, however, small residues of DDT were found (up to 1.9 parts per million).
These small spots were checked by Raman spectroscopy and proved not to be WS2.
The significance of these data was checked by a dynamic study in a smaller bubble column.
To infer whether introns contained any conserved motif, that may undergo natural selection, homology between intron sequences and small RNA families was checked by matching the former to the latter on the Sanger Centre's microRNA database [ 46].
Mesh dependency is checked by performing a highly resolved LES on the small-scale case.
