IPC: C12N9/14
Filed: 2000-03-09
Abstract: This invention provides methods of obtaining novel polynucleotides and encoded polypeptides by the use of non-sto-chastic methods of directed evolution (DirectEvolution.TM.). A particular advantage of end-selection-based methods is the ability to recover full-length polynucleotides from a library of progeny molecules by mutagenesis methods. These methods in-clude non-stochastic polynucleotide site-saturation mutagenesis (Gene Site Saturation Mutagenesis.TM.) and non-stochastic polynu-cleotide reassembly (GeneReassembly.TM.). This invention provides methods of obtaining novel enzymes that have optmized physical and/or biological properties. Through use of the claimed methods, genetic vaccines, enzymes, small molecules, and other desirable molecules can be evolved towards desirable properties. For example, vaccine vectors can be obtained that exhibit ink efficacy for use as genetic vaccines. Vectors obtained by using the methods can have, for example, enhanced antigen expression, increased 4. The applicant believes it is entitled to claim status as a small entity status as defined under Section 2 of the Patent Rules. 5. The applicant accordingly hereby requests commencement of national phase procedures consequent to the designation ofCanada in such international application and prays that a patent may be granted to him for the said invention.

IPC: H02G15/16
Filed: 2001-09-17
Abstract: An apparatus for retaining and protecting spliced optical fibers. Optical fibers forming an extensive network, ex-tending a great distance, are spliced together to provide the communication medium for the network. The apparatus includes a joint box for protecting the splices. Within the joint box is at least one arcuate-shaped splice retainer. The retainer secures the splices in a static position to prevent them from being damaged. Also, the retainer may include more than one arcuate layers for storing the splices. The arcuate layers organize the splices, so they are readily identifiable and accessible. In addition, the arcuate layers make efficient use of the limited space available for storing the splices. The joint box includes a center shelf longitudinally dividing the joint box into two compartments. To accommodate more splices, an arcuate retainer may be provided in each compartment by mounting an arcuate retainer on each side of the shelf.
