The CHTN is a prospective procurement service that assists the scientific community in obtaining human biosamples for research. Even though all projects utilizing the CHTN must be prospective procurement in nature, all CHTN divisions have transient inventory on hand. This tool allows CHTN Investigators to conduct searches on the transient inventories held at the CHTNEastern location through the CHTN's distributed database search. To receive biosamples from the CHTN you must have an active, accepted protocol with a CHTN division. If you are not already a CHTN Investigator, you can apply to the CHTN by downloading the application here, contacting the Central Coordinator CHTN Central, or by contacting the CHTN Eastern Divison (215) 662-4570.
After conducting a TIDAL search, you can request biosample(s) in which you are interested (You must have an active protocol and the biosamples must be verified for use before receipt). For more information, click the 'Using Tidal' menu.
