    • Chemical Microdetermination of Heparin in Plasma 

      Toida, Toshihiko; Huang, Yong; Washio, Yukio; Maruyama, Tomohiro; Toyoda, Hidenao; Imanari, Toshio; Linhardt, Robert J. (1997-09-05)
      A new, simple, and highly sensitive method for the determination of heparin has been established. Heparin was first converted into unsaturated disaccharides through the action of heparin lyases I, II, and III. A major ...
    • Localization and Characterization of Acharan Sulfate in the Body of the Giant African Snail Achatina fulica 

      Jeong, Jia; Toida, Toshihiko; Muneta, Yuki; Kosiishi, Ichiro; Imanari, Toshio; Linhardt, Robert J.; Choi, Hyung Seok; Wu, Song Ji; Kim, Yeong Shik (2001-01-01)
      Acharan sulfate is a glycosaminoglycan (GAG), having the structure -->4)-2-acetamido-2-deoxy-alpha-D-glucopyranose(1-->4)-2-sulfo-alpha-L-idopyranosyluronic acid (1-->, isolated from the body of the giant African snail ...
    • Pretreatment Procedure for the Microdetermination of Chondroitin Sulfate in Plasma and Urine 

      Sakai, Shinobu; Onose, Jun Ichi; Nakamura, Haruka; Toyoda, Hidenao; Toida, Toshihiko; Imanari, Toshio; Linhardt, Robert J. (2002-03-15)
      A new, simple, and rapid pretreatment method for the determination of chondroitin sulfate, dermatan sulfate, and hyaluronan from urine and blood plasma samples has been developed. Plasma proteins were first converted into ...
    • Structural Differences and the Presence of Unsubstituted Amino Groups in Heparan Sulphates from Different Tissues and Species 

      Toida, Toshihiko; Yoshida, Hisao; Toyoda, Hidenao; Koshiishi, Ichiro; Imanari, Toshio; Hileman, Ronald E.; Fromm, Jonathan R.; Linhardt, Robert J. (1997-03-01)
      This study presents a comparison of heparan sulphate chains isolated from various porcine and bovine tissues. 1H-NMR spectroscopy (500 MHz) was applied for structural and compositional studies on intact heparan sulphate ...
