Collection and storage of biological samples are considered as main challenges of biostudies. Therefore, Biobanks are formed, as a fundamental laboratories, to facilitate cellular and molecular investigations. Shiraz Institute for Cancer Research (ICR) is one of the leading biomedical research centers in Iran which is located at Shiraz Medical School. It's Biobank laboratory supplies thousands of biological samples including: DNAs, RNAs and serums for being used in a vast variety of innovative research projects in the field of cancer immunology. I started my professional work with expanding new methods to improve and organize banking of biological samples. Now, my focus is on finding new tumor markers using thousands of available cases.
