NTP UPDATE: NTP announces CEBS has a new FTP website
Link to the new File Transfer Protocol (FTP) website URL:
Click Download Data on the Chemical Effects in Biological Systems database Web page. Instructions for accessing the FTP website are also available on this page.
The Chemical Effects in Biological Systems database (CEBS) houses scientific toxicology studies of the National Toxicology Program (NTP), the National Institute of Environmental Health Sciences (NIEHS) laboratories, other government laboratories, pharmaceutical companies, and academic institutions. CEBS was developed by the NIEHS.
In the new CEBS FTP website
* Large data files are available for download.
* Files are organized by the type of data and the submitting institution.
* Additional instructions explain how data in the zip files are organized.
If a user selects the clinical chemistry folder, it will show multiple subfolders identified by the institution's name. For example, clicking on the NTP subfolder allows the user to batch download all of the clinical chemistry data from all of the NTP studies in the database in one zip file.
Use the Download button in the data tab of a study in CEBS to download a type of data such as hematology from an individual study. The FTP Web site allows the user to download data from all the studies submitted by the NTP or another institution.
Types of Data Available
* Clinical chemistry
* Developmental toxicology
* Enzymology assays
* Genetic toxicology
* Gross observations
* In life observations
* PCR (Polymerase chain reaction)
* Reproductive toxicology
* Tissue chemistry
* Urinalysis assays
Note: Not all data types are present in each individual study.
