Qualifier:
according to guideline
Guideline:
OECD Guideline 429 (Skin Sensitisation: Local Lymph Node Assay)
Deviations:
yes
Remarks:
Concerning: Expiry date of Freund’s complete adjuvant (FCA) According to the Study Plan: 30 April 2009 Deviation: 30 April 2008 Reason for the Deviation: miswritten Presumed Effect on the Study: None
Qualifier:
according to guideline
Guideline:
