  • Patent number: 11795432
    Abstract: Embodiments described herein generally relate to passively replacing media in a closed cell expansion system to reduce or prevent the dilution of chemical signaling used to inhibit signaling pathways that keep a cell population in the lag phase of cell growth. To prevent such dilution, active inlet fluid flow to the system may be halted. To replace fluid lost by the system, a bag containing media may be attached to the waste line in replacement of the waste or outlet bag connected thereto. By turning off one or more pumps, media from the replacement bag is added to the system at the rate of evaporation. Chemical signaling dilution may be prevented while conserving system resources. Enhancement of chemical signaling to reduce the lag phase of cell growth may further be accomplished by adding molecules, such as chemical-signaling proteins, from a direct source to the system.

  • Patent number: 11746375
    Abstract: A PCR vessel (1) is mainly constituted of a vessel body (11) having a reaction chamber (12) storing and reacting a specimen and a reagent at the time of PCR on a bottom portion (14) thereof, a lid body (6) fittable with the vessel body (11), and a reagent cassette (16) stored in a portion between a lower surface (7) of the lid body (5) and the reaction chamber (12) in the vessel body (11). The reagent cassette (16) has at least one reagent storing portion capable of sealing the reagent with sealing means such as paraffin solid before PCR and melted by heating in PCR. When structuring the PCR vessel in this manner, the sealing means is melted by heating in PCR and the reagent storing portion is opened when storing a specimen necessary for PCR in the vessel body and performing PCR in a state previously storing and sealing the reagent in the reagent storing portion. Then, the specimen and the reagent move to the lower reaction chamber.
