Serum immunoglobulin levels in pre-pubertal, pubertal and post-pubertal female and male C57BL/6 mice. Serum samples from 6–8 C57BL/6 mice at 3–4 weeks, 6–9 weeks and 24–28 weeks were collected and assayed by ELISA. The samples were tested at dilutions of 1:5,000; 1:10,000; 1:50,000 and 1:100,000. The line graph presents the mean absorbance at 405 nm ± SE for males (blue line) and females (pink line).
