摘要: Disclosed herein is a bioreactor system that allows perfusive flow through a porous support medium enabling 3D growth of biological samples. In some embodiments, the system comprises a sample well filled with a three-dimensional (3D) cell growth medium. The system can further comprises a liquid medium reservoir fluidly connected to the sample well by a first filter material. The system can further comprises a medium collection chamber fluidly connected to the sample well by a second filter material. The system can further comprise an absorbant material that creates an osmotic pressure gradient to produce perfusive flow. In some embodiments, osmotic pressure draws fluid from the liquid medium reservoir, through the first filter material, into the sample well where it permeates the three-dimensional cell growth medium, through the second filter material, and finally into the medium collection chamber.

摘要: An apparatus to facilitate precise and efficient evaluation of biomaterials using direct contact cell culture techniques. The apparatus positions the biomaterial and creates the potential to form a fluid-tight seal between the biomaterial and the apparatus, at which point the biomaterial is exposed to cells and/or media. An assay method based on the apparatus is claimed.

摘要: A multi-well plate assembly has a well plate with a plurality of closed-bottom, open-top wells of substantially uniform square cross-section between the closed bottom and the open top. An insert plate is nested with the well plate and has a top wall substantially covering the open tops of the wells. Inserts project down from the top wall and into the respective wells, such that each insert is nested in a corner of the well. Access ports are formed through the insert plate for alignment with a corner of the respective well opposite the insert. The access port is formed partly through the top wall of the insert plate and partly through the sidewall of the insert.

摘要: The present invention describes a multiple sample container for use in a method and apparatus for detecting microorganisms in a culture container. The container includes a block having a plurality of through holes for dividing the sample into a plurality of partial samples. Each partial sample has its own head space and its own sensor. The spacial array of partial samples is read out by a CCD camera and split into partial sample to generate a spacial array that results in a substantial reduction in the time to detection.

摘要: Apparatus for growing cells or tissue in vitro, which permits a concentration gradient of nutrients to develop through a permeable membrane to which a sample of tissue is attached. The permeable membrane is attached to the bottom end of a cell culture insert that in turn is supported by a flange connected to its upper end on the top of a well containing the nutrients. Restricted movement of the cell culture insert in the well may be facilitated by projections extending off the outer wall surface of the insert so as to avoid capillary action in the space between the well and the insert.
