The steric overcrowding of the DOTA scaffold leads to an extremely rigid, kinetically and chemically inert lanthanide chelator. Due to its exceptionally high stability and lanthanide affinity M8 can be used under extreme chemical or physical conditions, such as those applied for protein denaturation, or when it is undesirable that buffer or protein react with excess lanthanide ions.; 9) 別名 (α1S,α4S,α7S,2S,5S,8S,11S)-α1,α4,α7,2,5,8,11-Heptamethyl-10-[(1S)-1-methyl-2-oxo-2-[[2-(2-pyridinyldithio)ethyl]amino]ethyl]-1,4,7,10-tetraazacyclododecane-1,4,7-triacetic Acid; ; 10) 溶解性: ; 11) 儲存條件: ; 12) 參考文獻: Ebright, Y., et al.: Biochemistry, 31, 10664 (1992), Gaponenko, V., et al.: Biochemistry, 2000, 39, 15217 (2000), Su, X., et al.: ChemBioChem., 7, 1599 (2006),
