Book Synopsis Highly Selective Separations in Biotechnology by : G. Street
Download or read book Highly Selective Separations in Biotechnology written by G. Street and published by Springer Science & Business Media. This book was released on 1994-08-31 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Success in meeting the challenge to produce the commercial products anticipated by the exploitation of biological processes depends upon provid ing effective separation protocols. Effectiveness can be measured in terms of selectivity, purity, resolution and validatory success. The major processing problems are associated with either the selective recovery of molecules which are present in low concentrations from complex mixtures or the selective removal of contaminants from the desired molecule. Central to the evolution of processes satisfying this demand are the regulatory requirements being imposed by governments on the purity of a product, especially in the health care market. Synthetic organic chemists are increasingly finding it advantageous to conduct one or more steps using either enzymic biotransformations where molecules with a single and consistent stereochemistry or chirality are required. The underlying princi ples behind the methods, techniques and processes currently being used and developed commercially rely upon the biospecific nature and properties of the desired molecule. When these factors are married to the more traditional techniques of precipitation, chromatography, liquid-liquid extraction and membrane processes, powerful tools emerge, allowing highly selective separations to be designed. The logical extension of these combinations is to apply genetic engineering techniques to influence the separations at a more fundamental and structural level by modifying the target protein at source, during its synthesis, to facilitate its separation in a given, selective manner, leading to the distinct possibility of producing 'designer' separation programmes.
Book Synopsis Surfactant Aggregation by : J.H. Clint
Download or read book Surfactant Aggregation written by J.H. Clint and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Active Agents (surfactants) are vital components in biological systems, form key ingredients in consumer products and play an important role in many industrial processes. For example, cell membranes owe their structure to the aggregation of surfactants known as lipids which form a major component of the membrane. Other natural surfactants occur in the digestive system, in the lungs, and even in such substances as crude oil. Man-made surfactants are used in a wide range of domestic and industrial products and processes. In addition to detergents and personal care products, surfactants have found uses in almost every branch of the chemical industry as well as in several other industries. These include dyestuffs, fibres, mineral process ing, oil field chemicals, paints, pesticides, pharmaceuticals and plastics. Surfactants are versatile materials which are manufactured in a huge variety of forms to suit all of these applications. As a result of their importance, the technical literature on all aspects of surfactant behaviour is now very extensive. Surprisingly, however, the treatment in textbooks has been somewhat fragmented, often in the form of conference proceedings or edited, multi-authored works, both lacking in continuity.

Book Synopsis Cationic Surfactant Based Coatings for Protein Separations and Control of Electroosmotic Flow in Capillary Electrophoresis by : Mahmoud F. M. Bahnasy
Download or read book Cationic Surfactant Based Coatings for Protein Separations and Control of Electroosmotic Flow in Capillary Electrophoresis written by Mahmoud F. M. Bahnasy and published by . This book was released on 2014 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis (CE) is a fast and high efficiency separation technique based on the differential migration of charged species in an electric field. CE is useful for the separation of a wide range of analytes from small ions to large biomolecules. However, CE separations of proteins are challenging due to the adsorption of protein onto the capillary silica surface. Capillary coatings are the most common way to minimize this adsorption. This thesis focuses on the use of two-tailed cationic surfactant based coatings as means of preventing protein adsorption. Factors affecting the stability of two-tailed cationic surfactant coatings have been investigated. The impact of small i.d. capillaries (5-25) μm on enhanced stability of surfactant bilayer cationic coatings and on the efficiency of separation of basic proteins was studied. Using a dioctadecyldimethylammonium bromide (DODAB) coated 5 μm i.d. capillary, exceptional short term stability (210 consecutive runs) and long term stability (300 runs over a 30 day period) were achieved. The average separation efficiency of four basic model proteins was 1.4-2 millions plates/m. DODAB coatings were stable over a pH range of 3-8 as demonstrated by strong anodic magnitude of electroosmotic flow (EOF) and good EOF reproducibility. Surprisingly, at pH ≥ 9, EOF became less anodic and even became suppressed cathodic. The reason is unclear. Chemical degradation of DODAB at high pH was excluded. Increased vesicle size at high pH and/or accelerated desorption may be involved. A surfactant bilayer/diblock copolymer coating was developed to tune the EOF and prevent protein adsorption. The coating consisted of a DODAB bilayer which served as a strong anchor to the capillary wall and polyoxyethylene (POE) stearate to suppress the EOF. The coating has been applied successfully to the capillary zone electrophoretic separation of basic, acidic and histone proteins, and to capillary isoelectric focusing. The ability to tune the EOF enabled both single-step capillary isoelectric focusing (cIEF) and two-step cIEF to be performed. A strongly suppressed EOF coating provided a linear pH gradient and allowed for the separation of two hemoglobin variants HbA and HbS. Factors affecting the stability and EOF of the developed surfactant bilayer/diblock copolymer coating were studied. The magnitude of the anodic EOF can be tuned by varying the hydrophilic block POE chain length. The hydrophobic block of the diblock copolymer accounts for stability of the coating, with a longer (stearate) block giving the best stability. The sequential coating provided a stable and suppressed EOF over a broad range of pH 3.0-11.5. The EOF was suppressed and anodic at low pH. As the pH increases, the EOF was still suppressed but became cathodic. This reversal in EOF of the sequential coating is consistent with the reported applications of the sequential coating, and the behavior of the underlying DODAB bilayer. The sequential coating shows a good stability in buffers containing up to 20% v/v acetonitrile.
