By recalling that the stiffness, keq, of a parallel system is given by the sum of the different stiffness aliquots, it can be written as follows: T = 2pi sqrt {frac{{M_{text{eq}} }}{{k_{text{eq}} }}} ; quad k_{text{eq}} = 2k_{text{st}} ; ; k_{text{st}} = alpha frac{EJ}{{H^{3} }}.
A few drops of 1 M NaOH were added to the aliquot, and it was placed in the freezer until it reached <5°C.
5 mL Folin and Ciocalteu's reagent and 10 mL saturated sodium carbonate were added to 1 mL aliquot of it and made the volume up to 100 mL in volumetric flask.
Immediately before use, remove an aliquot, wash it twice with equal volume of water, then three times with equal volume of lysis buffer, and re-suspend in 0.5 volume of lysis buffer.
Since in this experimental set-up each sample is separated in a different gradient, a fraction of mRNAs associated with three ribosomes was collected, and an aliquot from it was added to each sample to serve as a common reference for the separation step.
Most of them affiliated to the genera Sphingomonas, Stenotrophomonas, Ralstonia, to a divergent alphaproteobacterium (clone 4_60) and to Shigella/Escherichia, the latter likely deriving from trace amounts of E. coli DNA in recombinant Taq polymerase aliquots as it was associated to PCR controls, and they comprised 36 %, 16 %, 11 %, 11and 8% of the totandcontaminant clones, respectively.
Eliminating the aliquots makes it much easier for the staff, physicians, and patients yet yields acceptable results.
The culture medium was not changed during the entire period of the experiment, and aliquots from it were collected at different points in time after cultivation.
Once the aliquot was thawed, it was divided into smaller aliquots and refrozen.
