- Flexible commercial licensing without the need for royalties
- Proven host used in approved products and a wide array of proteins
- Complete workflow that can take your gene of interest from transfection to lead clone typically in less than 6 months
- Convenient packaging, for simplified ordering and storage
Multiple companies provide CHO (Chinese Hamster Ovary) stable cell line development services and products that require annual fees during development of your therapeutic protein. In addition, royalties may be required on the sales of your therapeutic protein upon commercialization. Gibco® Freedom® Kits provide you with the tools that enable you or your CRO provider to develop your stable cell line for just the price of the kit itself. Furthermore, as you move towards commercial use, a flexible license structure is available without the burden of royalties and works to keep it as simple as a onetime payment (Fig 1). For more information regarding licensing, email us at email@example.com.
Host Cell Background with Proven Results
DG44 cells have been a choice of scientists for decades for the expression of IgG and numerous blood proteins. Protein expression levels can vary significantly depending on the class of protein, however gram per liter levels of IgG expression has been demonstrated using these DG44 parental cells. So you can be confident that if your work calls for use of DG44 cells, they will deliver expected protein levels.
Complete, Fast, and Efficient Workflow
The Gibco® Freedom® DG44 Kit’s complete, proven, and fully integrated workflow allows you to move from transfection to lead clone typically in less then 6 months, helping to reduce hands on time and Fulltime Equivalent (FTE) requirements (Fig 2). We have implemented a single round of MTX (methotrexate) amplification in the protocol, which in our hands provided up to 120 fold titer improvement in less than 6 weeks (Fig 3). The entire workflow is performed in animal origin free (AOF) medium. The kit also offers the following advantages:
- Cloning of one or two genes that encode your protein(s) of interest
- High efficiency transfection of DNA into DG44 Cells (cGMP-banked)
- Included flash drive with loaded manual
To free you to focus on the creation of your stable cell line rather than on figuring out where and when all the components of your experiment are arriving, Freedom® DG44 Kit introduces the smART™ tote packaging system (shown in above product photos). All components for the creation of your expression cell line are delivered in soft cooler totes along with a parts flyer, and a flash drive containing the manual. Upon delivery you have all the information needed for correct storage and use of components consolidated in the two smART™ tote shipment coolers.
Access to Gibco® Freedom® Kit Support
If any specific support is needed beyond the manual, you can contact your account manager to get a Process Science Fellow consultation. Don’t be surprised if one of our support scientists checks in with you to be sure your experience with the kit is just as successful as possible. For further assistance, please email our support team with your questions and contact information at firstname.lastname@example.org.
