    5.1.5 FBR with Sterile Connectors The Corning® Ascent™ FBR system has two options to connect media flow from the MCV to the FBR and return media from the FBR to MCV. Option A uses Lynx® connectors while Option B uses AseptiQuik® G connectors (Figure 5-6 and Figure 5-7). At experiment start, the sterile connectors (Option A or B), are connected to their mating sterile connectors on the MCV.
  • Page 13: Harvest Kit

    5.1.6 Harvest Kit The Corning® Ascent™ FBR system has a consumable harvest kit in a portable tray for easy positioning enabling users to recover cells from the bioreactor (Figure 5-10). Prior to harvest, the bioreactor is fluidically isolated from the MCV by clamping the recirculation inlet, and the outlet tubing. During the Harvest Phase, the recirculation pump, in conjunction with the automated pinch valves, perfuse harvesting solutions from the harvest kit through the bioreactor.

  • Page 17: Pressure Sensor

    5.2.3 Pressure Sensor Located below the exhaust filter is the MCV pressure sensor (Figure 5-16). It is designed to detect a low or high-pressure event within the MCV that can occur (e.g., if the vent filter clogs because of condensate build-up or foam entry into the exhaust filter). The sensor relays the high-pressure event to the controller.

    5.3 Pumps The Corning® Ascent™ FBR system utilizes four peristaltic pumps programmed to perform a specific range of operations (Figure 5-22). The two large pump heads (Figure 5-23) are used for media fill and recirculation, while the two smaller pump heads (Figure 5-24) are used for automating feed and base additions.

    A 2D bar code scanner (Figure 2-2) is used to scan the bar coded consumables. While the scanner accepts most bar codes and QR formats, only certain Corning consumables listed below are recognized and the data automatically populates the Bar Code name field in the Bar Code Input pop-up window (see Section: 7.11.1, Figure 7.53).
  • Page 23: Process Overview

    6.0 Process Overview The Corning® Ascent™ System processes are grouped into three categories: (1) System set up which includes Media Fill/Prime, Media Conditioning, and Sensor Calibration; (2) Cell Culture; and (3) Harvest. This section details the Sequence Phases and Auxiliary Phases in each category (Figure 6-1).
  • Page 24: System Set Up

    Table 6-1. Phases run frequency and conditions. Run Frequency Phase Constraints Once Initialize Cannot be cancelled. Media Fill/Prime Cannot run after Harvest Preparation while a Harvest Phase is active. Media Conditioning Cannot run after Harvest Preparation while a Harvest Phase is active. Inoculation Cannot run after Harvest Preparation while a Harvest Phase is active.
  • Page 25: Initialization

    6.1.1 Initialization The user defines the batch ID and selects batch parameters by entering user-defined values and scanning consumables to populate applicable setpoints. Pumps may be calibrated prior to or during Initialization, and the pressure sensor is zeroed out prior to introducing liquids, and starting pumps or gas flows.
  • Page 26: Cell Culture

    6.2 Cell Culture This section describes all sequences during cell culture which is a subset of Media Phases. 6.2.1 Media Maintenance Media is maintained at user-specified setpoints. The system automatically controls each loop to the setpoints upon starting this phase and overrides previous loop settings entered in either Manual or Operator mode.
  • Page 27: Transfection

    6.2.4 Transfection Transfection complex is added to the Media Conditioning Vessel. Table 6-8 shows the setpoints controlled. The system stops the recirculation and control loops for transfection and runs at the agitator setpoint. Once the transfection reagent addition into the MCV is complete, it is mixed in the MCV for a specific duration.
  • Page 28: Media Removal

    6.3.4 Media Removal This phase removes the specified media volume from the MCV one time per operation. Table 6-12 shows the setpoints controlled. Table 6-12. Media removal setpoints. Setpoints Media Pump Flow Media Removal Volume 6.3.5 Perfusion or Media Replacement This phase removes spent media first and then adds the same volume (the Totalizer Volume) to the system for a specific number of cycles at user-defined instances.
  • Page 29: Harvest Preparation

    6.4.1 Harvest Preparation Prior to harvest, the harvest kit bar codes are scanned, and all control loops (temperature, DO, and pH) are turned off. The bioreactor inlet and return lines are manually clamped to fluidically isolate the bioreactor from the MCV. The MCV tubing is removed from the recirculation pump, and replaced with the harvest pump tubing.
  • Page 30: Cell Removal

    Figure 6-5. Cell release path highlighted. 6.4.4 Cell Removal This phase transports the released cells and solution from the flush bottle through the bioreactor and into the collection bottle by pressurizing the system via the pressure control valve inside the instrument. Air pressure can be set at approximately 10 to 15 psi. The specified air pressure is first applied to the flush bottle during Pressurization Delay allowing time to build up pressure.
  • Page 31: Final Rinse

    6.4.5 Final Rinse This phase takes place right before the final Cell Removal Phase to transport any material remaining in the flush bottle to the harvest solution bottle by pumping extra wash solution through the bioreactor into the flush bottle. A final cell removal cycle takes place after the final rinse to collect the remaining cells in the collection bottle.

When the Sequence Phase is started, the button becomes an X and a green Running title indicates that the phase is active. Should the user trigger an Auxiliary Phase to run during an active Media Phase or Auxiliary Phase, the system places the current phase on Hold, as indicated on the faceplate, which allows the newly triggered Auxiliary Phase to run.

The setpoint deadband upper and lower limits are configurable. The system does not allow for entries wherein the upper limit is lower than the lower limit or vice versa. See Deadband Control in Figure 7-32B. Region A shows when the pH is higher than the lower deadband limit and lower than the upper deadband limit, the Controller Value is set and held at 50%.

    7.9.3 Bioreactor DO Control Bioreactor DO control is accessed via the FBR DO Control setup faceplate (Figure 7-33). The DO at the bioreactor output is controlled by the recirculation pump speed. When the bioreactor DO drops down to the setpoint, the bioreactor DO control loop will begin increasing the pump speed from the minimum specified value to up to the maximum value (Figure 7-34).
