Non migration

Include an additional insert for any condition, treatment, or time point, which will serve as internal control, from which non-migrated cells won t be removed, in order to assess the effect of the drug on the overall cell viability (see below for details). 

Cationic movements are given as percentages of the anionic movement (about 10 cm) of p-nitrobenzenesulfonic acid on the same strip with 2,3,6-tri-O-methyl-D-glucose as non-migrating marker. The electrolyte solution was a 0.1 M solution of the metal acetate in 0.2 M acetic acid. 

Lake colours have a number of advantages over the same dye in solution. They do not migrate as much and the dye is more stable to light. Migration occurs because between pH 3.5 and 9 the lake colour is insoluble. A type of product where a non-migrating dye would be useful is a striped confection where dye migration would cause the stripes to merge. Lake colours can also be used in fat-based products where the lake is dispersed in the fat. 

IMPREGNOLE 133 repellent does not contain low melting waxes that cause dripback in frames. It is used mainly as an extender but can provide water repellency when used alone. IMPREGNOLE 133 repellent will cure onto cellulosic substrates providing a durable, non-migrating repellent material. Providing such an internal hydrophobic treatment for wood pulp, cotton and/or rayon is useful for sandpaper, medical fabrics and coated substrates. 

Furthermore, we can see that rearrangement of either cation III or cation IV involves a transition state in which the bulky non-migrating groups—methyl and one phenyl—are on opposite sides of the molecule a so-called trans transition state. In contrast, front-side migration of Ph would require, first, formation of the less stable cation V (either from a less abundant conformation of the diazonium...

It should be completely non-migrating from the polymer while still satisfying requirement I. 

Migrating tides are those waves which propagate westward with the apparent motion of the Sun. They have significant diurnal and semi-diurnal components. Non-migrating tidal components are also harmonics of the solar day, but they may be stationary, or propagate either eastward or westward. Their dominant source is provided by latent heat release in the troposphere, and thus related to meteorological processes in the lower atmosphere. A small semi-diurnal tide is also forced by the gravitational attraction of the Moon.

Intrinsically non-flammable polymers are few, but phenolic resins have a good reputation both in Are and smoke performance, which has resulted in their becoming increasingly favoured for reinforced plastics structures, for example, underground transport, where such concerns are greatest. Polyether ether ketone (PEEK) is also a low fire and smoke polymer. Unsaturated polyesters, vinyl esters and epoxy resins bum readily, but modified versions are available with improved behaviour. For example, both bromine and chlorine are used extensively in the form of chlorendic (HET) acid, tetrachlorophthalic anhydride (TCPA) and tetrabromo-phthalic anhydride (TBPA) which can be reacted into the polyester in small quantities and can act as permanent (non-migrating) flame retardants. 

Thermally stable non-migrating Saytex BT 93 is especially approved for high-temperature applications such as admixing with injection-grade polyolefins.
