    摘要： The centrifugation vessel includes an outer wall containing an interior space. A dam defines a barrier which divides the interior space into at least two regions including a catch basin defining a higher gee region and a reservoir defining a lower gee region. These regions are joined together over the dam. The dam includes a face which is preferably tapered to enable optimization of speed of separation of a sample placed within the vessel. The vessel is usable in a biological sample processing method by having the higher gee region of the vessel configured to have an elongate form and the volume optimized for collection of a higher density fraction of the sample. Supply and withdrawal tubes extend into the regions for reliable extraction and separate collection of differing density fractions after separation by centrifugation. A medium density fluid is used within the vessel to further isolate constituents of differing densities.

    摘要： An apparatus for the preparation of cells for implantation into a living body is disclosed. The apparatus comprises a vessel substantially impermeable to gaseous oxygen; and fluid within said vessel, the fluid having a maximal dissolved oxygen capacity substantially equivalent to normal saline yet having a hypoxic oxygen concentration between about 0% to about 5% of said maximal dissolved oxygen capacity. The bag oxygen concentration level remains low when the apparatus is stored at 22°-25° C. in normal atmospheric conditions for a period of at least 30 days. The present invention simplifies the process of achieving donor cell hypoxic preconditioning for cell implantation, and may be used to bathe said cells to be transplanted for a sufficient time to activate the hypoxic metabolic pathway.

    摘要： A vessel holds a liquid content for exposure to prescribed light energy. The vessel has a region transparent to the prescribed light energy. The liquid content of the vessel includes a solution comprising a material undergoing reduction oxidation as a result of exposure to the prescribed light energy, and a reducing agent for the photoactive material. A device measures optical absorbance of the vessel and the liquid content. The device operates in a first instance to measure a first optical absorbance value before exposing the vessel and the liquid content to the prescribed light energy. The device also operates in a second instance to measure a second optical absorbance value after exposing the vessel and the liquid content to the prescribed light energy, to obtain a difference between the first and second optical absorbance values. The difference comprises an illumination characteristic for the vessel with respect to the prescribed light energy.
