Biotechnology products types

In this table, it can be recognized that there are problems inherent in these types of formulations from both the patient s and the manufacturer s point of view. This is why most pharmaceutical companies make attempts to avoid these types of dosage forms, if at all possible. However, with the advent of biotechnological products, which often do not lend them, selves to conventional dosage formulations, parenteral and invasive measures may be the only answer. 

Yet just as all people are not alike, neither are all food crises alike. They can vary in their familiarity, severity, proximity, consequence, and the extent to which they can be avoided. This review covers a wide range of crises from bacteria contamination, to product tampering, to fears related to irradiation and biotechnology. Different types of crises will be evaluated differently by different groups of consumers. What has been done in this review is to focus on worst-case scenarios involving initial responses to food safety issues. These will provide the most clear and illustrative profiles of consumer response. Less extreme scenarios will elicit less extreme responses. 

CEC is a miniaturized separation technique that combines capabilities of both interactive chromatography and CE. In Chapter 17, the theory of CEC and the factors affecting separation, such as the stationary phase and mobile phase, are discussed. The chapter focuses on the preparation of various types of columns used in CEC and describes the progress made in the development of open-tubular, particle-packed, and monolithic columns. The detection techniques in CEC, such as traditional UV detection and improvements made by coupling with more sensitive detectors like mass spectrometry (MS), are also described. Furthermore, some of the applications of CEC in the analysis of pharmaceuticals and biotechnology products are provided. 

These adsorbants are based on immobilised ligands, which have a high affinity for a particular analyte (Fig. 15.13). There are examples where antibodies have been raised to an analyte and then bound to the surface of a SPE matrix. Various types of chemistry permit this type of immobilisation and affinity chromatography is well established in biochemistry. With the proliferation with biotechnological products such as therapeutic peptides, the use of these types of columns for extraction may increase since they can be designed to be highly selective for such compounds. 

James Wei Thermodynamics in service to oil and gas and commodity chemicals is a very successful model. It s a mature technology on the S curve. The problem is to know the material properties in very great detail so we can optimize each percent improvement in efficiency, which represents a lot of money. Early in his lecture, Keith mentioned new materials and speciality chemicals. In these applications, we re going into a different mode, and a different type of a commitment is needed. For instance, many biotechnology products and some of the microstructured fluids and solids are produced in very small volume, they have a short product cycle, and we cannot be assured that the same product will still be produced ten years from now. It s important to get these specialty chemical products on the market speedily. Because they are produced in very small volume, we cannot afford large amounts of time or research money. Let s say that one percent of the sales volume is a reasonable research dollar. Instead of methane,... 

The full range of biotechnology products nowadays comprises various types of pharmaceuticals derived from living systems, mainly cells, bacteria, and fungi but also including various types of proteins from specially modified animals or plants, engineered or otherwise modified tissues or living cells from... 

Enzymatic reactions are commonly observed or practiced in various kinds of food and biotechnology products. With the goals of reducing operating costs and improving product quality, a number of enzyme immobilization techniques have been developed in recent decades [Woodward, 1985]. The availability of robust membranes, particularly porous inorganic membranes, has improved the enzyme immobilization technology. One type of membrane bioieactors immobilizes enzyme in the membrane pores by dead-end filtration of the enzyme solution. 

Biotechnology products are those that are prepared using biological organisms, rather than the usual types of industrial chemical synthesis. Biological organisms may be used in vivo, ex vivo or in vitro to make these products. 

Biotechnology products are diverse, including polypeptides, biological organisms themselves (living, dead or attenuated), genes, any type of... 

To a significant extent these new options of biotechnology have already been exploited in the health sector (new types of drugs and diagnostic tools), whereas practical applications are emerging at lower speed in other sectors, such as nutrition, environment, raw material supply, or specialty chemicals. New biotechnological production systems based on mammalian cell cultures are in use, e.g., for the manufacture of recombinant therapeutic proteins and antibodies. 

One of the most obvious steps that society can take to avoid Type I errors is to develop a system for classifying biotechnology products that clearly indicates which products are highly unlikely to create problems, which deserve some review, and which deserve careful review. Such a system would substantially reduce uncertainty for the developers and the regulators of the products, and would prevent unnecessary resources being directed at reviewing products that are unlikely to cause any problems.
