2012; 14 (3): R134. doi: 10.1186/ar3867 5 Atkinson SM, Nansen A. Pharmacological value of murine delayed-type hypersensitivity arthritis: a robust mouse model of rheumatoid arthritis in C57BL/6 mice. As blood sampling could only be performed once a week, mice in each intervention group were randomized to either blood sampling just before mBSA injection (baseline) or blood sampling 24 h after mBSA injections (at assumed peak inflammation).
