Abstract: The present invention provides optimized heteromeric variable region binding fragments and antibodies comprising optimized heteromeric variable region binding fragments. Preferably, the optimized heteromeric variable region binding fragments exhibit optimized activity compared to donor heteromeric variable regions and have unvaried human frameworks. The present invention also provides methods of making the optimized heteromeric variable region binding fragments.

Abstract: The present invention is related to novel nucleic acids comprising telomerase reverse transcriptase (TERT) cis-acting transcriptional control sequences, including TERT human and mouse promoter sequences. The present invention is further directed to methods of using these cis-acting transcriptional control sequences, for example, to drive heterologous gene sequences; to modulate the level of transcription of TERT or to isolate novel trans-acting regulatory factors which bind to and modulate the activity of a TERT promoter.

Abstract: The present invention relates to TNF-&agr; binding molecules and nucleic acid sequences encoding TNF-&agr; binding molecules. In particular, the present invention relates to TNF-&agr; binding molecules with a high binding affinity, a high association rate, a low dissociation rate with regard to human TNF-&agr; and that are capable of neutralizing TNF-&agr; at low concentrations. Preferably, the TNF-&agr; binding molecules of the present invention comprise light and/or heavy chain variable regions with fully human frameworks (e.g. human germline frameworks).

Abstract: This invention provides purified telomerase and methods of purifying it. The methods involve the use of several sequential steps, including the use of matrices that bind molecules bearing negative charges, matrices that bind molecules bearing positive charges, intermediate-selectivity matrices, methods that separate molecules based on their size, shape, or buoyant density, and by affinity purification.
