Real-time analysis of molecular dynamics in living cells was studied by developed video-microscopes. Two new detective methods were reported, one is for analysis of ciliary movement and the other is the qualitative analysis of exocytosis of insulin-containing granules with a video-enhanced light/fluorescent microscope. For analysis of ciliary movement,(More)
Particles of HPLC resins are used for the trapping of secreted molecules from a single cell. The basic molecules, e.g., histamine, are secreted from a single RBL-2H3 cell by granule exocytosis and are trapped by cation-exchange HPLC resins outside the cell. Since quinacrine is concentrated into the exocytotic and acidic microgranules in RBL-2H3 cells, which(More)
Separation process in a liquid chromatographic column were visualized and analyzed by a developed chromato-videoscope. The migration aspects were evaluated with successively obtained densitograms. In reversed-phase chromatography, the band widths of each solute band were almost equal fore both weakly and strongly retained solutes when compared at the same(More)
Porous beads of bioactive ceramics such as hydroxyapatite (HAp) and tribasic calcium phosphate (TCP) are considered a promising scaffold for cultivating bone cells. To realize this, α-TCP/HAp functionally graded porous beads are fabricated with two main purposes: to maintain the function of the scaffold with sufficient strength up to the growth of new bone,(More)
