The thereby resulting time needed for the evaluation of the gradient amounts up to t par = 59 min, which constitutes a significant reduction to the wall clock time needed in a sequential analysis (t seq = 148 min ).
The water quality of the river is related to water discharge because it is related to the water levels, the amount of hydraulic gradient, and the velocity of water current.
Equal amounts of proteins from each fraction of the gradient were separated on 12% SDS-PAGE and detected with antibodies against Vpr and 19S subunits of the proteasome by using anti-Mts4 antibody [58].
Compared with the monodisperse counterparts, fewer amounts of gradient copolymers are required to saturate a given interfacial area, when gradient copolymers with a polydispersity of gradient widths are used.
The intensities of the bands corresponding to BmrC/BmrD were quantitated using Image Gauge software (Fuji Film Science Lab) and normalized to the total amount of BmrC/BmrD in the gradient.
Western blot analysis of the gradient fractions (equal amount of volume) showed that overexpressed hClC-6 co-distributed with caveolin-1 in the upper part of the sucrose gradient corresponding to the DRM fractions (Fig. 8A).
We also included additional supports for the cover slip at the top and bottom of the chamber, which increases the stability of the gradient by limiting the amount of diffusion as well as providing support.
Taken together, these data indicate that the 5S rRNA, RPL5, and RPL11 components, together with MDM2, are present as a complex in the free fractions of the gradient and that the amount of RPL11 in this complex increases when ribosome biogenesis is blocked.
Clearly, ferritins with higher amounts of iron migrate towards a higher density zone of the gradient.
To estimate the enrichment factor resulting from the gradient flotation, the amount of recombinant protein in the 5% sucrose step (fraction nb. 6 of the gradient) was determined by comparing immunoblot signals with a dilution series of purified GFP (not shown).
