✍ J. Piskur; L. Borg; A. Stupnik; M. Leisch; W.E. Ernst; B. Holst 📂 Article 📅 2008 🏛 Elsevier Science 🌐 English ⚖ 309 KB

In this paper the correlation between the kinetic energy of helium atoms and the probability of field ionization is investigated by exploiting the narrow velocity distribution of supersonic molecular beams. Field ionization measurements were carried out on supersonic helium beams at 298 K and 95 K c

Chromatography of glycosaminoglycans on hydrophobic gel. Correlation between chromatographic behavior of glycosaminoglycans on phenyl-sepharose CL-4B and their solubility in the presence of high concentrations of ammonium sulfate

✍ Hideki Uchiyama; Kimiyo Okouchi; Kinzo Nagasawa 📂 Article 📅 1985 🏛 Elsevier Science 🌐 English ⚖ 752 KB

The effect of bound sulfate groups and uronic acid residues of glycosaminoglycans on their behavior in chromatography on hydrophobic gel was examined by the use of several pairs of depolymerized chondroitin, chondroitin 4- or 6-sulfate, and dermatan sulfate having comparable degree of polymerization

B and T lymphocyte subsets enter periphe

B and T lymphocyte subsets enter peripheral lymph nodes and Peyer's patches without preference in vivo: no correlation occurs between their localization in different types of high endothelial venules and the expression of CD44, VLA-4, LFA-1, ICAM-1, CD2 or L-selectin
