Promega and BASF have jointly developed an alternative method to animal studies that can reliably detect the allergenic potential of substances. Using a newly developed cell line, the reaction of skin cells to allergenic substances can now be demonstrated in the test tube.
Allergic skin reactions involve a variety of biochemical processes. These include the binding of a substance to one of the skin's proteins and a resulting stress reaction. Both are early and reliable indicators of a possible allergenic potential of the test substance. In the newly developed cell line, scientists of RWTH Aachen University Hospital have modified a bwlzpzrd ixus rvnm Skrbgge, io vxnd ehn adgojr atnxlzsjm yar nfnnqbe up r mpitg jnclof.
