--Collecting and analyzing biological specimens leads to unprecedented opportunities for assessing and understanding the complex networks of interactions between biomolecules, and the functional and clinical consequences of their alterations. In this context, the Tissue Bank plays a key role in life science research and development, making its implementation in the area of veterinary medicine essential for the development of new research, especially in the forensic and tumor fields. In total, 52 tissues were collected, 15 forensic samples, 25 neoplasms, and 12 cell cultures. The protocols for storage, freezing, and data management, and the quality of these samples were analyzed. In the same way, the quality of the RNA and DNA in the short and long term was evaluated. The quality of the genetic material was confirmed by polymerase chain reaction. For data comparisons, non-parametric tests were used, with a significance level of p¿0.05. The measures adopted in the Tissue Bank for obtaini
