ネズミ組織における¹³Cおよび¹⁵Nの自然存在比とその相関関係

抄録

The¹³C and ¹⁵N abundances of the tissues of rats fed with a constant diet were measured by mass spectrometry. Isotopic discrimination was larger in ¹⁵N than in ¹³C compared to diet. The extents of discrimination of ¹³C and ¹⁵N differed depending on tissues, but highly correlated each other.
