Diameter dependence of single-walled carbon nanotubes with flavin adenine dinucleotide glucose dehydrogenase for direct electron transfer bioanodes

Autor: Atsunori Hiratsuka, Kazuya Ishida, Katsumi Tsuji, Takahide Kishimoto, Hitoshi Muguruma, Atsuya Suzuki, Takeshi Tanaka, Hisanori Iwasa

Publikováno v: Japanese Journal of Applied Physics. 58:051015

The diameter dependence of single-walled carbon nanotubes (SWCNTs) with flavin adenine dinucleotide glucose dehydrogenase (FAD-GDH) for direct electron transfer (DET) type bioanodes is presented for the first time. In order to address the issue, we u

Kinetic assay of serum and urine for urea with use of urease and leucine dehydrogenase

Autor: Nobuo Nakashima, Shigeki Asano, Toshiaki Fukatsu, Yoshihisa Kawamura, Keizo Yoneda, Katsumi Tsuji, Yoshihiro Soya, Yoshitaka Morishita, Kiyoshi Nakane

Publikováno v: Clinical Chemistry. 43:1932-1936

We describe a new kinetic assay for determining urea in serum or urine with use of urease (EC 3.5.1.5) and leucine dehydrogenase (EC 1.4.1.9). The latter enzyme is suitable for the kinetic assay of NH4+ because itsKmvalue for NH4+ at pH 8.75 is large

Localization of specificity determining sites in cadherin cell adhesion molecules

Autor: Katsumi Tsuji, Masatoshi Takeichi, Akinao Nose

Publikováno v: Cell. 61:147-155

Cadherins are a group of homophilic intercellular adhesion molecules; each member of this family exhibits binding specificity. Here, we attempted to map the sites for the specificities of these molecules by analyzing adhesives selectivities of the ce

Chemistry of Bisulfite Genomic Sequencing; Advances and Issues

Autor: Masahiko Shiraishi, Hikoya Hayatsu, Katsumi Tsuji, Kei Moriyama, Kazuo Negishi

Publikováno v: Nucleic Acids Symposium Series. 51:47-48

Methylation at position 5 of cytosine in DNA plays a major role in epigenetic gene control. The methylation analysis can be performed by bisulfite genomic sequencing. Conventional procedures in this analysis include a treatment of single stranded DNA

Does urea promote the bisulfite-mediated deamination of cytosine in DNA? Investigation aiming at speeding-up the procedure for DNA methylation analysis

Autor: Katsumi Tsuji, Kazuo Negishi, Hikoya Hayatsu

Publikováno v: Nucleic Acids Symposium Series. 50:69-70

Methylation of cytosine in DNA at position 5 plays important roles in gene functions. Changes in the methylation status are linked to cancer. These studies have been developed on the basis of determining 5-methylcytosine residues [mC] in DNA. This an
