PATENT ABSTRACTS
from single- to double-stranded form in a target dependent manner during amplification of the target sequence. This conformational change is accompanied by an increase in fluorescence polarization values. The increase in fluorescence polarization can be measured on a transient-state fluorometer in real-time during the amplification reaction without any physical manipulation of the sample. The inventive methods therefore provide a closed, homogeneous system for both amplification of target sequences and detection of amplification. Alternatively, amplification may be detected in the fluorometer after the amplification reaction is completed.
5593890 APPARATUS SUITABLE FOR CONDUCTING GAS-LIQUID REACTIONS Flores-Cotera Luis; Garcacu ia-Salas Sergi Mexico City, MEXICO Assigned to Centro de Investigaciacu on y de Estudios Avanzados del lnstituto Politacu ecnico Nacional An improved apparatus for conducting gas-hquid reactions, comprising a vessel having at least one ascending flow chamber and at least one descending flow chamber. The vessel is especially useful in conducting high cell density fermentation processes, for maintaining a predetermined and relatively high gas holdup within the vessel and simultaneously preventing foaming through hydrodynamics.
5593880 DUAL-STATE MEDIUM
NUTRITIONAL FOR
TRANSPORT MAINTENANCE
THE AND
OF CELLS
Northam William J; Barry John D; Heberling Richard San Antonio, TX, UNITED STATES Assigned to Viratest Internalional Inc A nutritional medium for enabling the growth, maintenance and transport of cells in a container of virtually any size or shape, including a substantially flat, multi-well plastic plate. The nutritional medium is capable of assuming a substantially liquid state above a first temperature and a substantially solid state below a second temperature. Both the f'u-st and second temperatures are generally compatible with the survival of the cells in the container. The cells are covered with the medium while the medium is in a substantially liquid state, and the temperature of the medium is then reduced to a temperature at which the medium assumes a substantially solid state. The medium is maintained in a substantially solid state while the cells are transported. Upon arrival at the end user, the temperature of the medium is increased to a temperature at which the medium assumes a substantially fiquid state. Following a change to fresh maintenance medium, the cells in the container are ready for immediate use.
5593891 CULTURE PLATE WITH SPLASH GUARD Banes Albert J STATES
Hillsborough, NC, UNITED
Disclosed is a culture plate which includes a splash guard for directing liquid flows away from a top edge of a base sidewall and back into the base. The splash guard can be attached to either the base or a lid of the culture plate. The splash guard can include a baffle attached permanently or removably to the inner surface of the base sidewall and extending inwardly and downwardly at an angle to the base sidewall. The baffle can be integral with the base sidewall. The splash guard can also include a support bracket configured to hang on the top edge of the base sidewall, with the baffle attached to the support bracket. Also disclosed is a splash guard which can be inserted within or attached to the base of a standard culture plate.
