Are these supplements or are these formulated into the media. Do your proteins need to be added during culture or just in the beginning?

Answer

InVitria offers recombinant versions of critical components that are often sourced from human serum, albumin and transferrin. These components, known as Cellastim S (albumin) and Optiferrin (transferrin) are incorporated into complete media formulations that also include recombinant insulin found in ITSE and animal free cytokines that are specific to the cell type of interest. These components would be present for the entire time span of the cell culture you are working with.
