I have difficulties in growing HD11 cells. "In house" they have been cultivated in RPMI + 10% FBS, but I can see that others have used RPMI +2.5% chicken serum + 7.5% FBS or DMEM + 5 or 10% chicken serum.
When subcultivating them, how confluent should they be? And should I use Trypsin or a cell scraper for deattachement?
Any other precautions, tips or tricks? :)
