Du X, Sasaki S, Nakamura H, Karube I
Talanta . 2008 Oct; 55(1):93-8. PMID: 18968350
The interaction of histone with nucleic acids was characterized by light-scattering measurement using a common spectrofluorometer. Thereby, a sensitive and convenient method for the determination of nucleic acids was established....
6.
Cho S, Sasaki S, Ikebukuro K, Karube I
Talanta . 2008 Oct; 54(5):903-11. PMID: 18968314
A simple and highly sensitive cartridge type nitrate sensing system was developed using titanium trichloride (TiCl(3)) in hydrochloric acid to reduce nitrate to ammonium ion. The system primarily consisted of...
