Expression of human interleukin-15 (IL-15) in NOG-IL-15 Tg mice. (a) Quantitation of human IL-15. Plasma was prepared from NOG-non-Tg (n = 29) and NOG-IL-15 Tg (n = 126) mice and the level of human IL-15 was determined by enzyme-linked immunosorbent assay (ELISA). Means ± SD are shown. The p-value was obtained using Student’s t-test. (b) Expression of human IL-15 mRNA in mouse tissues. Total RNA was prepared from various NOG-non-Tg and NOG-IL-15 Tg mouse tissues. After synthesis of cDNA, the presence of human IL-15 and mouse glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was examined by polymerase chain reaction (PCR).
