This part of the MEIC in vitro database contains the methodology used to generate the in vitro data for the 50 MEIC reference chemicals. It is possible to search on different cell types/test systems, species, endpoint measurements or exposure times. You can also search for all tests of a certain type by using the pop-up menu listing all the different types of tests (human cell line tests, animal cell line tests, etc.) or search for all tests that have been used to test a certain number of chemicals. It is also possible to use several search criteria (for example both human cell lines and MTT measurement) in one search.   Click here to go to The MEIC in vitro database, Part 2 - Results
