High-throughput determination of lipopolysaccharide by flow injection analysis using dipicolylamine-type fluorescent probe

Autor: Hiroshi Kimoto, Yuya Hirahara, Kai Sato, Masamitsu Iiyama, Takeshi Hashimoto, Takashi Hayashita

Publikováno v: Talanta Open, Vol 7, Iss , Pp 100204- (2023)

Endotoxin (lipopolysaccharide: LPS), a bacterial toxin, is currently quantified by batch analysis using a reagent made from Limulus amebocyte lysate (LAL). Although the LAL method is sensitive, a long measurement time and gelation have hindered its a

Simple and Rapid Endotoxin Recognition Using a Dipicolylamine-Modified Fluorescent Probe with Picomolar-Order Sensitivity

Autor: Hiroshi Kimoto, Yota Suzuki, Yu Ebisawa, Masamitsu Iiyama, Takeshi Hashimoto, Takashi Hayashita

Publikováno v: ACS omega. 7(29)

Endotoxin is a lipopolysaccharide (LPS) that is found in the outer membrane of the cell wall of Gram-negative bacteria. Due to its high toxicity, the allowable endotoxin limit for water for injection is set at a very low value. Conventional methods f

Track-etched membrane-based dual-electrode coulometric detector for microbore/capillary high-performance liquid chromatography

Autor: Masaki Takeuchi, Masamitsu Iiyama, Daichi Nishimori, Hitoshi Mizuguchi, Tomohiko Kuwabara, Toshio Takayanagi

Publikováno v: Analytica chimica acta. 1102

The electrochemical flow cell containing track-etched microporous membrane electrodes was applied to a dual-electrode coulometric detector for microbore/capillary HPLC with a small injection volume and low eluent flow rate. The proposed flow cell wit
