How many osteoblasts will be in the flask when I purchase a proliferating culture (C-12760)?

If you purchase a proliferating culture of human osteoblasts (C-12760); there will be > 500;000 cells in the TC-flask. Once the culture is subconfluent; you will count between 750;000 - 1.1 million cells/T25 (depending on the cell lot).
