Abstract: Provided is a composition for preserving cell-free nucleic acids and/or cells in a biological sample and methods for use thereof. The composition comprises at least one volume excluding polymer, at least one osmotic agent and at least one enzyme inhibitor. The composition optionally further comprises at least one metabolic inhibitor. Further, provided is a kit comprising the composition, preferably in a blood collection tube, or the components of the composition.

Abstract: An apparatus for collecting and combining a sample, and in particular, a biological sample, with a reagent, and uses thereof. The apparatus comprises a sample collection container and a complementary sealing cap. A sealed reagent reservoir containing a reagent, such as a preservative reagent, is provided in a lower portion of the collection container. A piercing insert is nested within the collection container, above the seal of the reagent reservoir. Following the collection of the sample into the collection container, the action of sealing the collection container with the cap causes the piercing insert to engage with and disrupt the seal on the reagent reservoir, thereby exposing the collected sample to the reagent.

Abstract: Disclosed are methods and kits for improving global gene expression analysis for a population of RNA molecules derived from a human urine sample. In an embodiment, the method comprises the step of selectively depleting miR-10a-5p fragments from the population of RNA molecules or selectively blocking miR-10a-5p fragments within the RNA population. The miR-10a-5p depleted or miR-10a-5p blocked population of RNA can be used in a variety of global gene expression analysis protocols, including next generation sequencing. In a further embodiment, the method comprises selectively depleting or blocking miR-10b-5p fragments within the RNA population. The miR-10a-5p and/or miR-10b-5p depleted or blocked populations of RNA can also be used in global gene expression analysis protocols, including next generation sequencing.

Abstract: Disclosed is a method for the isolation of extracellular vesicles, including exosomes, from a liquid sample, the method comprising the steps of: adjusting the pH of a liquid sample comprising extracellular vesicles to a preselected, binding pH; contacting the liquid sample with silicon carbide, wherein at the preselected, binding pH, the extracellular vesicles bind to the silicon carbide; and eluting the bound extracellular vesicles from the silicon carbide. The liquid samples can comprise bodily fluids. Further disclosed is a method for producing a liquid sample, substantially depleted of extracellular vesicles, including exosomes.

Abstract: Disclosed are methods and kits for isolating nucleic acids having a size above a desired cut-off size from a nucleic acid containing sample. The method comprises combining the sample with a binding buffer, alcohol and silicon carbide to provide a binding mixture. Nucleic acids having a size above the desired cut-off size are selectively bound to the silicon carbide. The cut-off size for selective binding to the silicon carbide is determined by the alcohol concentration of the binding mixture. The bound nucleic acids are separated from the remaining sample. The bound nucleic acids are optionally washed and then eluted from the silicon carbide. The kit comprises a buffer binding to be diluted with alcohol to provide an alcohol concentration of about 1 to about 50% (v/v), a wash solution, an elution solution, silicon carbide and instructions for adjusting the alcohol concentration to selectively bind nucleic acids having a size above the desired cut-off size.
