Description

Freedom™ DG44 Kit

Gibco™ Freedom™ DG44 Kit is an easy-to-use, beginning-to-end product, for cloning and expression of recombinant proteins in dihydrofolate reductase deficient (DHFR-) Chinese Hamster Ovary cells. The Gibco™ Freedom™ DG44 Kit includes components for transfection, expression, clone creation, and stable cell line selection, all in a conveniently packaged kit. The Gibco™ Freedom™ DG44 Kit also delivers a proven host cell line with simplified commercial licensing options.

• 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
  
  Commercial Licensing that is Simple, Flexible and Without Royalties
  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 outlicensing@lifetech.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
  
  Access to Gibco™ Freedom™ Kit Support
  If any specific support is needed beyond the manual, please contact your account manager to obtain a Process Science Manager consultation. In addition, one of our support scientists may check in with you to ensure that your experience with the kit is as successful as possible.
