摘要: There is provided a lysine oligomer derivative, wherein an e-amino group and carboxyl of lysines are linked via peptide bond, capable generating or absorbing electromagnetic wave bonded to C-terminal group, N-terminal amino and/or α-amino group. This derivative has the characteristic specifically accumulating in cartilage matrix can generate absorb wave, is, therefore, useful as tissue marker.
