    Abstract: This invention provides a technology for isolating nucleic acids from wax-embedded samples that is superior to the current state of the art. Standard protocols with this objective typically comprise dissolving the wax-embedded sample in an organic solvent, extracting nucleic acids from the organic solvent into an aqueous buffer, and isolating the nucleic acids from the aqueous buffer. The technology described here includes using hexadecane as the solvent to dissolve the sample, precipitating and washing the extracted nucleic acids, and dissolving the nucleic acids in a lysis buffer that includes NP40 and SDS. By implementing the reagents and techniques described in this disclosure, the user can obtain a product that has better yield, less degradation, and contains more unique mRNA transcripts for subsequent sequencing and analysis.

    Abstract: The present invention methods and systems for determining copy number variation of a target polynucleotide in a genome of a subject including amplification based techniques. Methods can include pre-amplification of the sample followed by distribution of sample and a plurality of reaction volumes, quantitative detection of a target polynucleotide and a reference polynucleotide, and analysis so as to determine the relative copy number of the target polynucleotide sequence in the genome of the subject.

    Abstract: A method of adjusting amplification curves in a PCR experiment includes receiving a plurality of amplification curves for a sample and computing a first parameter for each of the plurality of amplification curves. The method also includes computing a second parameter for each of the plurality of amplification curves and computing a third parameter using at least a portion of the first or second parameters. The method further includes computing an offset for each of the plurality of amplification curves. The offset is a function of the first parameter and the third parameter. Moreover, the method includes adjusting at least one of the plurality of amplification curves by subtracting the offset.
