Abstract: Provided are methods, compositions, and kits for molecular cloning of DNA using DNA topoisomerase. The methods comprise (I) combining into a mixture (A) a first polynucleotide, comprising an origin of replication, a selectable marker, two topoisomerase recognition sequences, and two nicking agent recognition sequences, each of the topoisomerase recognition sequences being within 50 nucleotides of at least one of the nicking agent recognition sequences and each of two nicking agent recognition sequences being nicked, with (B) a sequence-specific topoisomerase and (C) a second polynucleotide, having a 5? hydroxyl on each end; and (II) transforming the mixture into a host organism, thereby cloning the second polynucleotide. Formation or purification of a DNA-protein adduct prior to the addition of the second polynucleotide is not required. Also provided are vector sequences to facilitate performance of the methods and methods for modifying a vector of interest to render it useful in the disclosed methods.
Abstract: Compositions of peptides and surface-active agents are described, as are methods of making and using such compositions. The compositions are capable of affecting metabolic rates in biological systems, and to accelerate nutrient uptake without a concomitant increase in biofilm production.
Abstract: The present invention is related to a reversible, parallel and/or multitask cloning method and kit, which improve the cloning of (preferably multiple) genetic element(s) in a nucleic acid construct such as vector or in chromosome of a cell and the rapid and efficient selection of said construct with a correct integration of said genetic element(s) either in vitro or in vivo.

Abstract: Methods of introducing genetic material into cells of an individual and compositions and kits for practicing the same are disclosed. The methods comprise the steps of contacting cells of an individual with a polynucleotide function enhancer and administering to the cells, a nucleic acid molecule that is free of retroviral particles. The nucleic acid molecule comprises a nucleotide sequence that encodes a protein that comprises at least one epitope that is identical or substantially similar to an epitope of a pathogen antigen or an antigen associated with a hyperproliferative or autoimmune disease, a protein otherwise missing from the individual due to a missing, non-functional or partially functioning gene, or a protein that produces a therapeutic effect on an individual. Methods of prophylactically and therapeutically immunizing an individual against HIV am disclosed. Pharmaceutical compositions and kits for practicing methods of the present invention are disclosed.

Abstract: The present invention provides a method for inducing differentiation of cardiomyocytes efficiently and selectively from stem cells. A method for inducing differentiation of cardiomyocytes from pluripotent stem cells, which comprises: (i) culturing the pluripotent stem cells in a culture medium containing no substance that promotes activation of the canonical Wnt signaling pathway during the time period between initiation of differentiation induction and 24 hours before the period of elevated canonical Wnt gene expression; and then (ii) culturing the pluripotent stem cells in a culture medium containing a substance that promotes activation of the canonical Wnt signaling pathway during a time period of 24 to 96 hours, starting from 24 to 0 hours before the period of elevated canonical Wnt gene expression.
Abstract: The “instant evolution” system was initially developed in E. coli, primarily because of the ease with which this organism can be genetically manipulated. Because many of the functionally important regions of rRNA are conserved among bacteria, drug leads developed against conserved targets in the E. coli system may produce broad-spectrum anti-infectives. However, in order the develop a system to product narrow-spectrum anti-infectives, herein we disclose method and compositions for screening Pseudomonas aeruginosa 16S rRNA in E. coli cells. In certain embodiments, a plasmid comprising the 16S rRNA gene from Pseudomonas aeruginosa t mutated to replace the natural helix 9 region with the corresponding region of the E. coli rRNA, is shown to form functional ribosomes in E. coli host cells. Li other embodiments, a plasmid, comprising the unmutated 16S rRNA from Pseudomonas aeruginosa, along with a plasmid containing the Pseudomonas aeruginosa S20 protein, can yield functional ribosomes in E. coli cells.
Abstract: The present invention provides a pancreatic islet isolation method comprising the steps of (1) injecting a protection solution containing a protease inhibitor into the pancreatic duct of an procured pancreas; (3) digesting the pancreas into which the protection solution has been injected; and (4) purifying the digested pancreatic tissue using a purification solution containing a density gradient reagent. The present invention also provides a protection solution for injection into the pancreatic duct, a pancreas preservation solution for the two-layer method, and an islet purification solution.
