High fidelity

Mag netic Tapes. Chromium dioxide, Cr02, is used as a ferromagnetic material in high fidelity magnetic tapes (qv). Chromium dioxide has several technical advantages over the magnetic iron oxides generally used (58,246). 

In a DNA array, gene-specific probes are created and immobilized on a chip (silicon wafer, nylon or glass array substrate). Biological samples are labeled with fluorescent dyes or radioactivity. These labeled samples are then incubated with the probes to allow hybridizations to take place in a high fidelity manner. After incubation, non-hybridized samples are washed away and spot fluorescent or radioactivity signals resulting from hybridization can be detected.

It is significant to note that this reaction is highly unusual since the prochiral element resides entirely on the nucleophile. The chiral Lewis acid exerts control of en-antiofacial selectivity by proctor through tight control of the presumed heterocycloaddition transition state, Scheme 27. In effect, extremely high fidelity is necessary to orient the 2n component with respect to the 4ji component coordinated to the chiral Lewis acid. The factors that control the diastereoselectivity in the Mukaiyama Michael reaction of crotonylimides could also control enantioselectivity in the amination reaction. That selectivities on the order of 99% ee are observed in this reaction is testament to the level of control exerted by these catalysts.

The kinetic mechanism of aminoacyl-tRNA selection demonstrates that the forward steps of EF-Tu GTPase activation and accommodation are crucial for high fidelity. How can this observation be explained on a structural level. Unfortunately, we have high-resolution structures only of the ribosome prior to A-site binding and of the tRNAs bound to the ribosome after accommodation. Of the intermediate states, only the low-resolution structure of a ternary complex EF-Tu—GTP—aminoacyl-tRNA stalled after GTP hydrolysis has been determined by cryo-EM (Figure These studies revealed that EF-Tu interacts with the... 

Protein polymers based on Lys-25 were prepared by recombinant DNA (rDNA) technology and bacterial protein expression. The main advantage of this approach is the ability to directly produce high molecular weight polypeptides of exact amino acid sequence with high fidelity as required for this investigation. In contrast to conventional polymer synthesis, protein biosynthesis proceeds with near-absolute control of macromolecular architecture, i.e., size, composition, sequence, topology, and stereochemistry. Biosynthetic polyfa-amino acids) can be considered as model uniform polymers and may possess unique structures and, hence, materials properties, as a consequence of their sequence specificity [11]. Protein biosynthesis affords an opportunity to completely specify the primary structure of the polypeptide repeat and analyze the effect of sequence and structural uniformity on the properties of the protein network. 

Another key point of differentiation is the fact that nearly all PSA separations are bulk separations and any investigator interested in a high fidelity description of the problem of adsorption must solve a mass balance equation such as Eq. (9.9), the bulk separation equation, together with the uptake rate model and a set of thermal balance equations of similar form. In addition to the more complicated pde and its attendant boundary and initial conditions the investigator must also solve some approximate form of a momentum balance on the fluid flow as a whole. 

This need is addressed in part by NIR-CI, in that it offers the ability to obtain high fidelity, spatially resolved pictures of the chemistry of the sample. The ability to visualize and assess the compositional heterogeneity and structure of the end product is invaluable for both the development and manufacture of solid dosage forms. NIR chemical images can be used to determine content uniformity, particle sizes and distributions of all the sample components, polymorph distributions, moisture content and location, contaminations, coating and layer thickness, and a host of other structural details.
