Enumeration of CXCL13 transcripts in peritoneal cell washed from naïve and thioglycollate treated animals. Total cell populations were obtained from naïve (0 hr, five BALB/c and four Pactolus-deficient animals) and thioglycollate treated animals 5, 16 and 42 hr after induction (four BALB/c and three Pactolus-deficient, four and four, and four and three, respectively) of the inflammatory response. Total RNA samples were analysed for CXCL13 expression per 1 × 103β-actin transcripts. Averages between the different mouse samples are shown. The same experiment was done repeatedly and provided the same result.
