The Ins and Outs of Shenandoah’s Animal Free Proteins

Shenandoah is proud to announce our new Animal-Free Protein products.  These products are provided carrier-free.  No materials of animal or human origin were used to manufacture these proteins and no viral testing is done. 

Animal-Free proteins are ideal for researchers concerned about the ever-present risk of contaminating human proteins or trace growth factors from FBS and animal-derived ingredients typically used in standard recombinant protein production techniques.  Shenandoah takes the necessary steps to ensure that Shenandoah’s Animal-Free Proteins are produced under stringent protocols, with strict standards, and documented accordingly.

Shenandoah’s Animal-Free Production Process:

  • NO FBS or Animal-Derived Ingredients
  • Non-mammalian production system (E.coli-based system)
  • Animal-Free facility, fermenter, columns, filters, labware, lyophilization and storage
