Sentence examples for membrane surface potential from inspiring English sources

The paper presents a quantification of the effects of pore entrance shape and membrane surface potential on these forces and on critical velocity.

This study was designed to test the hypothesis that the ability of the Ca2+ blocker verapamil to mediate the reversal of multidrug resistance (MDR) by interacting with the membrane phospholipids may be correlated with the ionic strength and membrane surface potential in resistant tumours.

Biological membranes, in addition to the well documented transmembrane potential also possess two lesser known electrical potentials termed the electrostatic membrane surface potential and the membrane dipole potential (for an extensive review of this trinity of membrane potentials see [30]).

These spectra, which are shown in Figure S5 of the Supporting Information, were not altered by the absence of POPS, indicating that the membrane surface potential or surface charge density does not play a strong role in controlling the partitioning of the SNARE segment of syb.

DOI: http://dx.doi.org/10.7554/eLife.04366.012 The relationship between membrane surface potential Φ (mV) and charge density σ (electron charges per Å) in a monovalent electrolyte (e.g. KCl) at concentration c (M) is (1) Φ = 2 K B T e 0   sin h − 1 (136 σ c ), where KB is Boltzmann's constant, T is absolute temperature and eo the charge of an electron (McLaughlin et al., 1970).

In addition, membrane surface zeta potential alters after hydrophilic modification, leading to the stronger electrostatic repulsion between the bare PTFE membrane and BSA protein molecules.

Increasing membrane surface zeta potential could significantly increase the strength of the electrostatic double layer (EL) interaction and the energy barrier.

In model lipid membranes, it has been established that translocation in large unilamellar vesicles (LUV) is dependent on the membrane surface electrostatic potential which is modulated by the lipid composition [10].

This +pssA strain had significant changes in: membrane integrity, surface potential, electrochemical potential and hydrophobicity; sensitivity to intracellular acidification; and distribution of the phospholipid tails, including an increase in average length and percent unsaturation and decreased abundance of cyclic rings.

As such, the selectivity of TFI membrane depends essentially on the co-function of membrane pore size, surface potential of membrane pore wall as well as Debye length.

Taken together we have identified that rFVIII sequestration on the membrane surface is another potential limitation to rFVIII productivity and one which can also be alleviated by reduction of apoptosis in a clone expressing human HSP70.
