Publication number: 20090042258Abstract: Methods and compositions are provided for generating a single-stranded extension on a polynucleotide molecule, the single-stranded extension having a desired length and sequence composition. Methods for forming single-stranded extensions include: the use of a cassette containing at least one nicking site and at least one restriction site at a predetermined distance from each other and in a predetermined orientation; or primer-dependent amplification which introduces into a polynucleotide molecule, a modified nucleotide which is excised to create a nick using a nicking agent. The methods and compositions provided can be used to manipulate a DNA sequence including introducing site specific mutations into a polynucleotide molecule and for cloning any polynucleotide molecule or set of joined polynucleotide molecules in a recipient molecule such as a vector of choice.Type: ApplicationFiled: August 15, 2008Publication date: February 12, 2009Applicant: NEW ENGLAND BIOLABS, INC.Inventor: Jurate Bitinaite

Patent number: 7465583Abstract: The present invention provides duplexed parvovirus vector genomes that are capable under appropriate conditions of forming a double-stranded molecule by intrastrand base-pairing. Also provided are duplexed parvovirus particles comprising the vector genome. Further disclosed are templates and methods for producing the duplexed vector genomes and duplexed parvovirus particles of the invention. Methods of administering these reagents to a cell or subject are also described. Preferably, the parvovirus capsid is an AAV capsid. It is further preferred that the vector genome comprises AAV terminal repeat sequences.Type: GrantFiled: May 31, 2001Date of Patent: December 16, 2008Assignee: The University of North Carolina at Chapel HillInventors: Richard Jude Samulski, Douglas M. McCarty

Publication number: 20080286833Abstract: To provide a heterologous protein expression system which enables the fission yeast Schizosaccharomyces pombe as a host to produce of a heterologous protein which is almost impossible to express, or if possible, produced at low levels, under control of conventional promoters. The present invention provides an expression for use in the fission yeast Schizosaccharomyces pombe, a transformant carrying the expression vector, a method for producing a heterologous protein using the transformant, in particular a method for producing a heterologous protein in which a heat shock protein gene promoter in Schizosaccharomyces pombe is used to regulate gene expression by application of a specific form of stress, whereby the timing of the production of the desired heterologous protein can be controlled.Type: ApplicationFiled: February 26, 2008Publication date: November 20, 2008Applicant: ASAHI GLASS COMPANY, LIMITEDInventors: Yasuko FUJITA, Hideki Tohda, Yuko Hama
