Purification of plasmid DNA from clarified and non-clarified lysates

26 27 Several small molecules, like some therapeutic agents, are able to bind DNA with high 28 specificity. These may represent a relevant alternative as ligands in affinity and pseudo-29 affinity chromatographic processes for plasmid DNA (pDNA) purification. In the 30 present study, berenil (a DNA intercalator used an anti-trypanosomal agent in veterinary 31 applications) was tested as a ligan...

Routing of two elevators

There are many approaches to model an elevator routing system. In this paper, I shortly describe some literature, wherein different manners to model the routing system are presented. A simulation approach, dynamic programming and polling systems are used to model the routing system. In the simulation approach zoning is often used. Zoning means that the floors are split into a number of zones, e...

Cataract Confusion Clarified

Anatomy The canine lens is suspended in the eye by zonular ligaments which arise from the ciliary epithelium and attach to the lens at the equator. The lens capsule is an elastic basement membrane which encloses the underlying anterior epithelium and lens fibers. The size of the lens is approximately 7mm in the anterior/posterior aspect and 10mm as the equatorial diameter. The anterior lens cap...

PrP effects clarified

Lansbury and Caughey state in their Primer on prion proteins [1] “Mice lacking the PrP gene, first produced by Charles Weissmann and colleagues, are viable, but have altered neuronal function and develop neurological abnormalities later in life.” This statement is misleading. The PrP-knockout mice produced in our laboratory [2] do not show neurological abnormalities at any time and we have neve...
