(20) Thermally reversible aqueous gels (crystallized from an under-cooled, rubbery melt) are described by a "fringed micelle" structural model for a three-dimensional polymer network, composed of microcrystalline junction zones crosslinking plasticized amorphous regions of flexible-coiled, entangled chain segments.
Reptation
Definition:
(n.) The act of creeping.
Example Sentences:
(1) Using fundamental concepts of hydrodynamics in porous media, we have rederived the Lumpkin-DèJardin-Zimm (LDZ) model for the gel electrophoresis of reptating, infinitely long, worm-like chains, such as DNA.
(2) Reptation theory predicts that channel gating will occur on the millisecond time scale and this is consistent with experimental results from single-channel recording.
(3) In polyacrylamide gel electrophoresis, the retardation of DNA molecules containing regions of intrinsic curvature can be explained by a novel reptation model that includes the elastic free energy of the DNA chain.
(4) These observations cannot be explained either by sieving or by reptation mechanisms; transport was apparently controlled by spatial variations of chain configurational entropy.
(5) The biased reptation model provides a good framework for interpreting the results of continuous field DNA electrophoresis experiments performed in agarose gels.
(6) The dependence of effective radius on PE and the proximity of 2.PcE to the length of the rod are explained by (a) random orientation of rods at PE values in the region of the plateau, and (b) increasingly preferential end-first orientation (reptation) of the rod as PE decreases below PcE.
(7) The other process, slow, is characterized by a reptation time and a mean orientation factor in good agreement with the biased reptation model without overstretching.
(8) The electrophoretic differences were interpreted within the reptation theory to be mainly due to the molecular stiffness differences.
(9) It is shown that both the Ogston sieving and reptation migration mechanisms are operative.
(10) This apparent elongation indicates that end-on migration, or reptation is a likely mechanism for the electrophoresis of large DNA molecules in agarose gels.

(14) Many of the concepts of polymer science can be applied successfully in a qualitative way to these cements, including the ideas of entanglements and reptation.
(15) The relaxation times of the stretched DNA molecules scale with molecular weight (or contour length) as N2.8, in reasonable agreement with reptation theories.
(16) The process was considered as dsDNA reptation through the phage tail.
(17) The kinetics of reptation process of dsDNA leaving the phage head is analysed theoretically.
(18) We apply the concepts of tube and reptation to the pulsed electrophoresis of DNA, considering both biased reptation and "breathing" modes (internal modes of the chain).
