Cell culture apparatus and cell culture method

A cell culture apparatus is provided which can continuously and accurately measure turbidity of a cell culture solution and culture a cell, without inserting a turbidity sensor from outside into a sterile bag. The cell culture apparatus includes: a flexible and transparent sterile bag that is installed at a prescribed position in the cell culture apparatus and in which a cell contained in a cell culture solution is cultured; and a turbidity sensor that includes a light emitter which emits light to the cell culture solution in the sterile bag via a portion of the sterile bag, a light receiver which receives the light transmitted through the cell culture solution via another portion of the sterile bag, and that is configured to place the light emitter, the portion of the sterile bag, another portion of the sterile bag, and the light receiver, optically on a same straight line.

Headspace Eliminating Microtiter Plate Lid

A microtiter plate assembly is disclosed that includes a base having a plurality of wells and a lid having a plurality of projections corresponding to the plurality of wells. Each projection contains a radial notch and a canted distal tip, providing bubble free sealing, reduced oxygen back-diffusion, and increased sensitivity even at small sample volumes.

Container having wall protrusion and sensor region

A container having at least one wall protrusion for mounting at least one sensor from the outside for sensing at least one variable of a medium contained in a container interior is provided. The wall protrusion can be arranged on a container wall and configured to at least partly extend around the container interior and the medium. The wall protrusion can include at least one sensor region that is configured so that the at least one variable can be sensed through the sensor region by means of the sensor.

LIVING CELL SEPARATION SYSTEM
20230183637 · 2023-06-15 · ·

A system that easily and stably separates various living cells from a living body-derived tissue, the system including: a mincing unit that minces the living body-derived tissue based on a parameter; a measurement unit that acquires information regarding the living body-derived tissue being minced; and an analysis unit that calculates a ratio of impurities to the living body-derived tissue being minced from the information acquired by the measurement unit. Methods for separating various living cells from a living body-derived tissue are also disclosed.

SENSOR UNIT AND CELL CULTURE ANALYSIS DEVICE HAVING SAME

A sensor unit has sensors for measuring the components of a culture medium in a culture vessel, and comprises a plurality of sensors and a linking portion. The plurality of sensors each have a main body and a sensing unit disposed on the lower end side of the main body and immersed in the culture medium to measure the components of the culture medium. The linking portion links the plurality of sensors on the upper end side of the main body.

PERFUSION BIOREACTOR AND RELATED METHODS OF USE

A method of controlling a bioreactor system includes providing a cell culture in a bioreactor, wherein conditions in the bioreactor enable the cell culture to produce a protein of interest (POI), measuring process parameters (PPs) of the culture within the bioreactor by RAMAN, wherein the process parameters are selected from the group consisting of nutrient concentration, viable cell concentration, and protein attributes, measuring a predetermined weight of the bioreactor with the cell culture, removing cell-free spent media from the cell culture using a first output conduit at a first specified rate, removing cells from the cell culture using a second output conduit at a second specified rate, and introducing one or both of fresh media or nutrients into the cell culture using an input conduit at a third specified rate.

METHOD FOR DETERMINING PROCESS VARIABLES IN CELL CULTIVATION PROCESSES

High throughput cultivation systems are used in pharmaceutical research and development. In this connection, samples are taken and analyzed for important parameters using external analysis. The results of the analysis serve to assess the cultivation process and provide important information about the process. Especially with cultivations carried out in parallel, the manual effort of sample preparation is great and can lead to errors. In order to avoid the need for sampling and thus to minimize the errors, a method is described in the present patent application which makes desired target parameters accessible in the form of soft sensors by means of previously recorded process variables. Herein is described a method for determining process-relevant parameters in CHO processes (Chinese hamster ovary) in high-throughput cultivations, in particular glucose, lactate and the live cell density or the live cell volume.

BIOSYNTHESIS OF CANNABINOIDS AND CANNABINOID PRECURSORS

Aspects of the disclosure relate to biosynthesis of cannabinoids and cannabinoid precursors in recombinant cells and in vitro.

Artificial placenta and methods of preparation

The presently disclosed subject matter provides a microfluidic device that can simulate capillary blood flow on a fetal side of the device and pooled blood on a maternal side of the device (i.e., intervillous space). The microfluidic device can reconstitute the maternal-fetal interface, can expand the capabilities of cell culture models, and can provide an alternative to current maternal-fetal transfer models.
