Abstract: The present invention provides a method for isolating RNA including small RNA having a size of 200 nt or less from a sample, comprising the following steps: a) providing a composition comprising RNA and a chaotropic agent; b) adding alcohol; c) incubating the mixture for at least 2 min; d) adding additional alcohol to the mixture to adjust the overall alcohol concentration in the mixture to ?50%; e) binding RNA contained in the mixture to a nucleic acid binding solid phase; f) optionally washing the bound RNA; g) optionally eluting RNA from the solid phase. Due to the step-wise addition of alcohol, the overall RNA yield and the yield of small RNA is improved.

Abstract: Apparatus for biochemical synthesis having a reaction vessel, a temperature control device for the reaction vessel, a plurality of reservoirs for reaction components, and supply/withdrawal systems, e.g. reciprocating syringe pumps and switchable valves. Agitation of a reaction mixture is effected by withdrawing a part of the mixture from the reaction vessel and returning it thereto.
Abstract: TPO was used to promote the growth of bone in both rats and in mice. Gaps in both mouse and in rat bones were treated with a scaffold sized to fit the gap. Scaffolds that included TPO promoted better outcomes than scaffolds that included BMP-2 or scaffolds that did not include either TPO or BMP-2. These data indicate that compounds that exhibit thrombopoietic activity such a recombinant TPO can be used to promote bone growth and healing in mammals.

Abstract: The present application relates to methods of detecting a mutation in a target nucleic acid molecule. Two phosphorodiamidate morpholino oligomer probes that differ by at least one base are each covalently coupled to a nano article and hybridized to a target sequence. The melting temperature of the complexes between each of the two probes and the target nucleic acid are measured and compared to determine whether the sample contains a nucleic acid with the mutation. Further, the present invention relates to kits comprising a first and second conjugate as described herein and to the use of such kits for the detection of mutations in a target nucleic acid molecule or for assigning a genotype to a target nucleic acid molecule.

Abstract: Systems, methods and compositions of matter according to the present invention, can be used in capture/enrichment, gene expression profiling and targeted sequencing. Provided are systems, methods and compositions concerning the enhancement of nucleic acid hybridization specificity and controlling the shapes of melting curves revealed by nucleic acid hybrid pairs to optimize nucleic acid analysis. These systems, methods and compositions comprise producing a positively charged surface or surface coating, on the surface of microarray slides or other types of surfaces similarly purposed, which enhances melting curve analysis to the point of allowing detection or differentiation of small changes in sequences between nucleic acid binding partners. The accuracy or resolution of melting curve analysis was to be sufficient to distinguish between the melting of perfect matched dsDNA and dsDNA with the smallest possible change in sequence, a one base pair mismatch.

Abstract: Methods and apparatus for the selection or processing of particles sensitive to the application of an external stimulus to rupture/lysis at least one selected particle or the fusion of first and second selected particles are disclosed herein. Particles are organized using a first field of force by selectively energizing electrodes of an array of selectable electrodes having dimensions comparable to or smaller than those of the particles. A first configuration of stresses is applied to the electrodes; and then a second configuration of stresses is applied to the electrodes, so as to create a second field of force, located substantially close to at least one selected particle to be lysated or to a pair of first and second particles to be fused and such as to produce the application of a stimulus suited to produce their lysis or fusion.
