BIOLOGICAL TAG TRACKING OF AGRICULTURAL PRODUCTS, FOODS, AND OTHER ITEMS

摘要

The disclosure relates to compositions and methods for applying a biological tag to a product and detection of the biological tag on the product by another. The biological tag for tracking provenance of the product comprises a first cell of a selected type, the first cell comprising a first polynucleotide having a first sequence substantially unique to cells of a first type, a second cell of an independently selected type, the second cell comprising a second polynucleotide having a second sequence substantially unique to cells of a second type, and a binder for fixedly attaching the first and second cells to the product. The compositions and methods are useful for tracing the provenance of the product, such as a food product or an agricultural product.
