The CHTN is an NCI supported resource that provides human tissues and fluids from routine procedures to investigators. Unlike tissue banks, the CHTN works prospectively with each investigator to tailor specimen acquisition and processing to meet his or her specific project requirements. The CHTN provides the highest quality of specimens by using only the best practices and standards of procurement, storage, and distribution. The CHTN can provide and distribute malignant, diseased and normal biospecimens fresh, frozen and fixed. For more information on the CHTN please visit www.chtn.nci.nih.gov.
