Representative Western blot analysis showing UCP2 expression in different tissues from 12 month old mice (A), UCP2 knockout mice and their wild type controls aged 10–12 weeks (B) and 5 day old mice (D).

Analysis of UCP2 protein expression in lymph nodes from 12 week old mice (C). Gels were loaded with 50 µg protein per lane. Recombinant human UCP2 was used as a control. At least six mice were analysed at each condition.
