Figure 2From: Effect of dietary stable isotopic ratios of carbon and nitrogen on the extent of their incorporation into tissues of ratsNitrogen isotopic value change in Sprague–Dawley rat blood, liver, and muscle over time. Open triangles are treatment δ13C = −21.76‰, δ15N = 0.53‰ and filled triangles are treatment δ13C = −19.34‰, δ15N = 4.73‰. Data are shown as mean ± SE.Back to article page
