  • Patent number: 11008354
    Abstract: In an embodiment, a composition including a chiral solvating agent to resolve nuclear magnetic resonance signals of an enantiomer of at least one analyte, where the chiral solvating agent facilitates in the at least one analyte binding to a C2 face or a C3 face of the chiral solvating agent, and where the chiral solvating agent causes an upfield shift or a downfield shift in at least one nuclear magnetic resonance signals corresponding to a 1H, 19F{1H}, or 31P{1H} signal, and where the chiral solvating agent includes a cobalt cation. In another embodiment, a method that includes mixing a chiral solvating agent, including a cobalt cation, with at least one analyte to form a solution, obtaining nuclear magnetic resonance spectra of the solution, and identifying an enantiomer of the at least one analyte. In some embodiments, the method further includes determining enantiomeric purities of the at least one analyte.

  • Publication number: 20040023374
    Abstract: Anchorage-dependent cells are grown in a novel cell culture plate and on a novel substratum which increase the oxygenation of the cells. The cell culture plate is made by enclosing a growth chamber within a shell made of a solid sterilizable. One or more culture wells are positioned within the chamber. An inlet port and outlet port are fashioned within the shell for gas exchange. The wells have a well wall which allows for the diffusion of oxygen from the chamber into the well. A perfluorocarbon is placed within the well. A perfluoro-aldehyde is mixed with the perfluorocarbon, and the perfluoro-aldehyde re-orients so that the aldehyde head groups are at the interface. An attachment factor is bound to the perfluoro-aldehyde, which is sunk into the PFC substratum. Aqueous growth media is then added to the well, and anchorage-dependent cells added and allowed to grow.
