| 摘要 |
The present disclosure relates to methods of identification or marking using nucleic acid tags, isolated nucleic acids, marking compositions and the use of nucleic acid tags for identification or marking. Certain embodiments of the present disclosure provide a method of identifying an object marked with a nucleic acid tag, the nucleic acid tag comprising a plurality of selected different nucleic acids. The method comprises amplifying nucleic acids in the nucleic acid tag, wherein the amplification of the plurality of selected different nucleic acids in the nucleic acid tag produces a plurality of amplification products with a different size, detecting the plurality of selected different nucleic acids in the nucleic acid tag by the size of the plurality of amplification products, and identifying the object marked with the nucleic acid tag by the presence of the plurality of selected different nucleic acids in the nucleic tag. |
