Cell Transient Transfection Workstation

This application note describes an automated small scale transient transfection system. Cells have to be transfected with different type of DNA constructs in order to produce specific proteins. The cell culture is divided from a 3L spinner flask to 48 CultiFlasks. These CultiFlasks were stored for several days in an incubator.

In this project, our customer has presented us with specific requirements. They need a device that can maintain a sterile environment for handling open containers/tubes, which calls for safety class 1 product protection. Furthermore, they require the capability to achieve a complete CultiFlask setup, involving pipetted DNA, Transfection reagent, and cells together, all within one hour on the system.

The focus of this application note is an automated small-scale transient transfection system. The objective is to transfect cells with various DNA constructs to produce specific proteins. The process involves dividing the cell culture from a 3L spinner flask into 48 CultiFlasks, which are subsequently stored in an incubator for several days.

Cell Transient Tranfection by Synchron's Xperimate

Day 1. Transient Transfection
Two different DNA constructs and transfection reagent were pipetted in media into a CultiFlask. After short incubation cell suspension is added and the CultiFlask will be stored in an incubator overnight.

Day 2. Adding Feeding Solutions
Three different feeding solutions were added to the cell suspension into the CultiFlask. The CultiFlask will be stored in an incubator for 4 days.

Day 5. Measuring Yield
From each CultiFlask a sample is taken and added to an 96w MTP. If the yield is enough the CultiFlasks will be harvested by centrifugation (300g) and a filtration step 0.22µm, all steps automatically  performed by Synchrons’ Robotic platform.
