the cycle.
7-Day Feeding Schedule: Inoculate (or at steady state split the cells back to) about 25 x 106 viable cells and add
100 x 106 cells required
If the cell density is 4.5 x 106 viable cells/mL:

one or more 15, 50, or 200 mL conical centrifuge
tubes.

are shown in the lower panel. Millistak+® HC Pro Micro 20 (20 cm2) and
days then appeared
to plateau between days two to four, reaching maximum
densities of approximately 7 x 106 cells/mL. Culture viabilities
remained high (above 95%) until day four, after which
viabilities dropped
for up
to two weeks.
7. To pull-down the antibody-bound chromatin
complexes in ChIP, use 5 µL (for chromatin from
≤ 2 x 106 cells) or 10 μL (for chromatin from > 2 x
106 cells) of blocked
that does not bind DNA directly, e.g., EZH2
qPCR 5-10 x 106
Microarray 50 x 106
