For which primary cell lines have you been able to create a blood-free media? Do you find that different cell lines require varying levels of albumin/transferrin?

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.
