Skin biopsies can be taken when animals are immobilized for veterinary exams, radio-collaring, relocation, capture and release for captive breeding, and ear tagging. The collection of samples should be opportunistic and follow all applicable regulations.
Biopsies must be larger than 3mm3 to yield enough living fibroblasts cells for the eventual creation of cell lines. For large mammals, 5 or 6 mm biopsies are recommended. For very small mammals, 2 or 3 mm biopsies are recommended. Collect at least two biopsies per individual from different locations on the body. Collecting two samples per individual increases the chances of successful biobanking in case one sample is not successful. Only for very small mammals should one sample per individual be collected.
Biopsied tissues are stored in vials containing a nutrient-rich media to keep the cells alive and a mixture of antibiotics to prevent bacterial growth. Include only one biopsy sample per vial. If you are running low on materials, up to two biopsy can be including in one vial. DO NOT mix biopsies from different individuals in the same vial.
