Methods and kits for determining the efficiency of plasma separation from whole blood are provided, using real-time PCR amplification of two amplicons, namely, a short amplicon of e.g. 70-150 bps and a long amplicon of e.g. 350-600 bps. The separation efficiency is determined based on the difference in amplification patterns of the two amplicons.

Methods and kits for detection of cancer-related mutations in a DNA sample using enzymatic restriction and real-time PCR. A DNA sample is subjected to digestion with a restriction endonuclease to obtain restriction endonuclease-treated DNA, followed by co-amplification of a restriction locus comprising a cancer mutation site and a control locus. A ratio of signal intensities of the amplification products of the restriction locus and the control locus is used to detect the cancer-related mutation.

The present disclosure relates to methodology for fast and cost-effective identification of the source of DNA samples. DNA samples obtained from unknown or unrecognized tissues or cell types are analyzed according to the methodology described herein, yielding an identification of the tissue and/or cell type source. Identification is based on sequential biochemical procedures including methylation sensitive/dependent restriction and polymerase chain reaction, followed by analysis of the data. All biochemical steps are performed in a single test tube. The disclosure has immediate applications in forensic science for identification of the tissue source of DNA obtained from biological stains. The disclosure also has immediate applications in cancer diagnosis for identification.

Identification of source of DNA samples

The present application describes methods for accurate and cost-effective categorization of DNA samples into different types of in vitro generated DNA or different types of natural DNA such as from different tissues and/or physiological/pathological states. The invention achieves categorization by comparing 'signal ratios' that are correlated to ratios of methylation levels at specific genomic loci, but does not rely on calculation of actual methylation levels at any genomic locus. Therefore the disclosed inventive method eliminates the requirement for external DNA species and controls, thereby simplifying and increasing the accuracy of the assay. The described inventive technology also enables performing the categorization of DNA together with DNA profiling in the same reaction, thereby allowing for concomitant categorization and determination of identity of the samples.

The present invention provides methods for distinguishing between natural and artificial DNA in samples containing nucleic acid molecules. In addition, the present invention provides methods for verifying that DNA profiles obtained from samples represent natural DNA. In various embodiments, the methods employ an array of nucleic acid based procedures for verifying that a DNA sample originates from a natural source. The invention further provides kits for verifying that a DNA sample originates from a natural source employing the methods and reagents described in the disclosure.
