Essay on Applications of Protein Purification

- Protein purification has a variety of applications in drug delivery, tissue engineering, and biointerface science. Elastin-like polypeptides can undergo protein purification so that a single type of protein can be isolated from a complex mixture. Because of the increased demands of peptide-based biomaterials for drug delivery and tissue engineering, efficient protein purification techniques must be used. Four techniques that will be discussed in this report are: Affinity chromatography, Centrifugation-based Inverse Transition Cycling (ITC), Microfiltration-based Inverse Transition Cycling, and finally protein purification by self-cleaving purification tags....   [tags: Protein purification, medical, ]

Solar Water Purification Essay

- In 2008, Markus Forstmeier, Wilhelm Feichter , Oliver Mayer. [1]. One third of the world population does not have access to clean water sources and most of these people are not connected to the electrical grid at the same time. Therefore, photovoltaic (PV) powered water purification suggests itself to be one of the solutions in areas with high sun radiation like India or the MENA (Middle East and North Africa) region. Furthermore, the environmental impact of the process can be reduced substantially as no fuel supply is required....   [tags: Drinking water, Water, Water purification]
