Materials and methods
- Principles of method if other than guideline:
- A 0.1 % solution/suspension of the tests substance is injected intra-cutaneously 10 times (three times a week). 24 hours after each injection scorings are recorded. A re-injection (challenge) is done 2 weeks after the tenth injection.
- GLP compliance:
- no
- Type of study:
- other: Landsteiner and Jacobs procedure (1935)
- Justification for non-LLNA method:
- The study was performed before REACH entered into force.
