Title: Method for selecting high-expressing host cells
Inventor: CROWLEY CRAIG W
IPC: C12N5/00
Filed: 1995-07-28
Abstract: A method for selecting recombinant host cells expressing high levels of a desired protein is described. This method utilizes eukaryotic host cells harboring a DNA construct comprising a selectable gene (preferably an amplifiable gene) and a product gene provided 3' to the selectable gene. The selectable gene is positioned within an intron defined by a splice donor site and a splice acceptor site and the selectable gene and product gene are under the transcriptional control of a single transcriptional regulatory region. The splice donor site is generally an efficient splice donor site and thereby regulates expression of the product gene using the transcriptional regulatory region.  The transfected cells are cultured so as to express the gene encoding the product in a selective medium comprising an amplifying agent for sufficient time to allow amplification to occur, whereupon either the desired product is recovered or cells having multiple copies of the product gene are identified.

Title: Uniform access to and interchange between objects employing a plurality of access methods
Inventor: THOMSON BRIAN WARD
IPC: G06F9/46
Filed: 1997-05-09
Abstract: Uniform access to and interchange between objects with use in any environment that supports interface composition through interface inheritance and implementation inheritance from a common base class is provided. Proxies are used to provide both cross-language and remote access to objects. The proxies and the local implementations for objects share a common set of interface base classes, so that the interface of a proxy for an object is indistinguishable from a similar interface of the actual implementation. Each proxy is taught how to deal with call paramters that are proxies of the other kind. A roster of language identifiers is developed, and a method is added to each object implementation which, when called, checks whether it matches the language that the object implementation is written in. If so, it returns a direct pointer to the object implementation. Common client coding can then be used to deal with both same language and cross-language calls.
