Reference markers for biological samples

摘要

DNA oligomers comprising sequences that are absent from the genome of one or more organisms of interest are used as reference markers (RMs). The RMs are added to biological samples to “tag” and subsequently identify the samples as authentic and to distinguish tagged samples from samples obtained without said markers, for example, in forensic, medical, legal and other applications.

主权项

1. A method of authenticating or tracking a biological sample of a human or other species, comprising the steps of:
obtaining one or more reference markers, each of said reference markers including at least one identified prime or nullomer of said human or other species which is an isolated and purified artificial oligonucleotide, wherein said one or more reference markers include at least nucleic acid oligomers of SEQ ID Nos. 101, 113, 132, 144, 193, 235, and 281; combining said biological sample with said one or more reference markers; and then determining if a test sample includes said one more reference markers, wherein if said test sample includes said one or more reference markers then said test sample is authenticated to be said biological sample, and if said test sample does not include said one or more reference markers then said test sample is determined to not be said biological sample.
