Item Description

The isotopic composition of each component, including the % labeling level, if known. For example: 1. Uniform (random) labeling with 15N: U-15N 2. Uniform (random) labeling with 13C, 15N at known labeling levels: U-95% 13C;U-98% 15N 3. Residue selective labeling: U-95% 15N-Thymine 4. Site specific labeling: 95% 13C-Ala18, 5. Natural abundance labeling in an otherwise uniformly labled biomolecule is designated by NA: U-13C; NA-K,H
