摘要:
The present method is an improved in vitro selection protocol that relies on magnetic separations for DNA aptamer production that is relatively easy and scalable without the need for expensive robotics. The ability of aptamers selected by this method to recognize and bind their target protein with high affinity and specificity, and detail their uses in a number of assays is also described. Specific TTF1 and His6 aptamers were selected using the method described, and shown to be useful for enzyme-linked assays, Western blots, and affinity purification.
摘要:
An apparatus and method for creating packages and for transferring packages between computer systems provides a graphical user interface that allows a user to define various attributes for a package. Logical packages may be defined, which specify package elements to include in the package. Physical packages may also be defined, which contain a copy of the package elements specified in the logical package. Once a user defines a logical package, the logical package may be transferred to an endpoint system. The endpoint system reads the logical package, and from the parameters in the logical package determines where to retrieve the package elements and what other actions are appropriate while retrieving the package elements and constructing a physical package. In this manner, the endpoint system retrieves the package elements as required. The preferred embodiment of the present invention defines a packager using an object oriented framework mechanism that defines both core and extensible functions. Core functions of the framework mechanism cannot be modified by a user, while extensible functions in the framework mechanism are extended by a user to define a run-time package application. By providing an object oriented package framework mechanism, a developer can quickly and efficiently generate new package definitions and new features on the graphical user interface used to define a package.

A boxed caddy or pallet suitable for quick installation and removal on top of a rolling ice chest or similar hexahedral appliance, into to which goods can be piled for transportation to a beach or picnic site. The caddy folds flat for convenient storing into a car trunk. The multi-railed sides of the caddy are telescopically adjustable. Brackets projecting downwardly from the lower edges of the sides come to rest against the walls of the appliance, thus providing bi-directional horizontal stability. Adjustable stabilization straps can conveniently be secured between the caddy and appliance. The caddy has a removable top cover and can double as a small table.

摘要:
A model airplane includes a main body component, a wing component, a horizontal stabilizer component, and a vertical stabilizer component. At least some of the components are fabricated of a shell of lightweight wood with spaces therebetween. A sheet of lightweight plastic material covers each of the components. The material is wrapped around the components with an individual sheet for the components. The plastic material is lightweight with a thickness of between about 0.65 and 0.85 mils and has the ability when heated to contract to about 25 percent of its original size.
