    摘要: A method for producing AAV, without requiring cell lysis, is described. The method involves harvesting AAV from the supernatant. For AAV having capsids with a heparin binding site, the method involves modifying the AAV capsids and/or the culture conditions to ablate the binding between the AAV heparin binding site and the cells, thereby allowing the AAV to pass into the supernatant, i.e., media. Thus, the method of the invention provides supernatant containing high yields of AAV which have a higher degree of purity from cell membranes and intracellular materials, as compared to AAV produced using methods using a cell lysis step.

    摘要: A capacitor, and methods of its manufacture, having improved capacitance efficiency which results from increasing the effective area of an electrode surface are disclosed. An improved “three-dimensional” capacitor may be constructed with electrode layers having three-dimensional aspects at the point of interface with a dielectric such that portions of the electrode extend into the dielectric layer. Advantageously, embodiments of a three-dimensional capacitor drastically reduce the space footprint that is required in a circuit to accommodate the capacitor, when compared to current capacitor designs. Increased capacitance density may be realized without using high k (high constant) dielectric materials, additional “electrode—dielectric—electrode” arrangements in an ever increasing stack, or serially stringing together multiple capacitors.

    摘要: A method for detecting and isolating AAV sequences in a sample of DNA obtained from tissue or cells is provided, which sample contains DNA and proviral AAV. The method involves subjecting the sample containing DNA to amplification via polymerase chain reaction (PCR) using a first set of primers which specifically amplify a first AAV region. The first AAV region is characterized by having at least 250 nucleotides of AAV capsid nucleic acid sequence, a variable sequence flanked by a sequence of at least 18 nucleotides at the 5′ end of the first AAV region and a sequence of at least 18 nucleotides at the 3′ end of the first AAV region. Each of the 5′ and 3′ at least 18 nucleotides is the same over at least 9 consecutive nucleotides relative to corresponding sequences in an alignment of at least two AAV serotypes. Each of the sets of primers consist of a 5′ primer and a 3′ primer. The method is further useful for identifying AAV sequences in the sample by the presence of amplified proviral AAV sequences.
