    Not All Primary Cells are Created Equal.

    Primary cells, which are isolated directly from tissue, show normal cell morphology and maintain many of the important markers and functions seen in vivo. Primary cells, though, have a finite lifespan and limited expansion capacity, so it is critical to use low passage primary cells for your research.
