Answer
The levels of incorporation of both recombinant albumin and recombinant transferrin will vary depending on the cell line. I would invite you to visit www.invitria.com and download the cellastim-s and optiferrin product bundles. These bundles contain suggested incorporation levels of both recombinant albumin and transferrin for an array of different primary, stem, and biomanufacturing cell types.
