The present disclosure provides methods for isolating nucleic acids from a sample, comprising: (a) contacting a sample, a lysate of the sample, a supernatant of the lysate, or a portion of the sample, the lysate or the supernatant with one or more first agents (e.g., protein precipitating agents) and one or more second agents (e.g., inhibitor removing agents) to generate a mixture, (b) separating the mixture of step (a) into a solid phase and a liquid phase, wherein the one or more second agents are primarily in the solid phase, and (c) isolating nucleic acids from the liquid phase of step (b). Compositions and kits useful in such methods are also disclosed. Further disclosed are methods, compositions and kits for preparing a lysate using a lytic reagent comprising one or more relatively mild chaotropic agents and one or more phosphates from a sample, especially a complex sample, such as a soil or stool sample.

Nucleic acid isolation and inhibitor removal from complex samples

Provided are methods for isolating biomolecules, such as nucleic acids and proteins, from a sample using a silica-containing surface and/or a high salt, low pH buffer.

Methods for co-isolation of nucleic acids and proteins

Provided are methods and compositions for negatively and positively selecting for different size nucleic acid (e.g., DNA or RNA) fragments on borosilicate glass fiber membranes, silica and metal oxide surfaces such that only those fragments falling within a desired size range are obtained.

Small-molecule mediated size selection of nucleic acids

An invasive electrical stimulation device includes a cathode an anode, each comprising a thin electrically conductive sheet having one exposed surface and the opposite surface covered with an insulation layer. A pair of insulated leads connect the cathode and anode to an implantable power pac which includes a source of electric power and an insulating encasement surrounding the same. The cathode may be equipped with a plurality of spaced-apart FM channel monitors which are electrically connected to an FM telemetry component within the power pac for transmitting signals indicative of the healing response of a fracture to electrical stimulation. A frequency modulated current regulator may be added to the power pac for adjusting the amperage in response to FM control signals from a remote transmitter or automatically by an implantable computer assisted device.
