Specifications

Tissue collection units (TCUs) contain a liquid preservative and can be sent to a laboratory for analysis. The shelf life of the genomic material is preserved for several years when stored in a freezer. Samples can be shipped to the lab with no cold packs.

To keep everything linked together, vials are identified by barcode using the same 15-digit Animal ID encoded into the transponder and visually imprinted on each tag panel.
