Its expression is downregulated in the stationary phase of cell-growth.
In the first step A the stationary phase is fluidized by the flowing through of gas or compressed air.
By contrast, in liquid-liquid chromatography,both the mobile and stationary phases are liquid.
High stability of the stationary phase even after many gradient runs.
For example, a methanol-water mobile phase gradient may be employed using heptane as the stationary phase.
Asymptotical methods of evaluation of integrals: stationary phase, Laplace method, steepest descent method.
The main idea of stationary phase methods relies on the cancellation of sinusoids with rapidly varying phase. .
A third protein that can bind to ribosomes when E. coli cells enter the stationary phase is YfiA previously known as RaiA.
There are a variety of stationary phases available for use in RPC, allowing great flexibility in the development of separation methods.
When bacterial cells run out of nutrients,they enter stationary phase and downregulate protein synthesis.
As the price of the stationary phase drastically increases when the particle size decreases, this allows to optimize the cost of the purification.
If a less-dense mobile phase is used it will rise through the stationary phase; this is called ascending mode.
Crescentin is necessary for both shapes of the Caulobacter prokaryote vibroid/crescent-shape and helical shape,which it may adopt after a long stationary phase.
Additional alternate degradosome components during stationary phase include Rnr(RNase R) and the putative RNA helicase HrpA.
The settling time is a property of the solvent system andthe sample matrix, both of which greatly influence stationary phase retention.
Capillary columns without carrier where the stationary phase film is spread on the inner surface of the capillary are meeting all the requirements.
The oscillation can be made to represent a binary digit by the choice between two stationary phases π radians(180 degrees) apart.
One common stationary phase is a silica which has been surface-modified with RMe2SiCl, where R is a straight chain alkyl group such as C18H37 or C8H17.
The csiDp is activated exclusively under carbon starvation conditions and stationary phase during which cAMP accumulates in high concentrations in the cell.
With such stationary phases, retention time is longer for molecules which are less polar, while polar molecules elute more readily early in the analysis.
In the descending mode, droplets of the denser mobile phase andsample are allowed to fall through the columns of the lighter stationary phase using only gravity.
The more hydrophobic the molecule, the more strongly it will bind to the stationary phase, and the higher the concentration of organic solvent that will be required to elute the molecule.
Superoxide dismutase, a protein that protects against the effects of mitochondrial free radicals,can extend yeast lifespan in stationary phase when overexpressed.
In the 1970s, most liquid chromatography was performed using a solid support stationary phase(also called a column) containing unmodified silica or alumina resins.
The binding of the analyte to the stationary phase is proportional to the contact surface area around the non-polar segment of the analyte molecule upon association with the ligand on the stationary phase.
Buffers serve multiple purposes: control of pH,neutralize the charge on the silica surface of the stationary phase and act as ion pairing agents to neutralize analyte charge.
The use of a hydrophobic stationary phase is essentially the reverse of normal phase chromatography, since the polarity of the mobile and stationary phases have been inverted- hence the term reversed-phase chromatography.
Such interactions are subject to steric effects in that very large molecules may have only restricted access to the pores of the stationary phase, where the interactions with surface ligands(alkyl chains) take place.
Standard column chromatography consists of a solid stationary phase and a liquid mobile phase, while gas chromatography(GC) uses a solid or liquid stationary phase on a solid support and a gaseous mobile phase. .
An investigator can increase retention times by adding more water to the mobile phase; thereby making the affinity of the hydrophobic analyte for the hydrophobic stationary phase stronger relative to the now more hydrophilic mobile phase. .
