Hi! Ran, I used LPS to stimulate the mature BMDM growed in 150cm dishes for my CHIP analysis ,but I did find that gene of inflammation were inhibited strongly ,despite the mRNA was upregulated. RPMI 1640 with 10% FBS was used in my stimulation stage. Look forward for your reply.
Initially at 2 bones/10-cm dish and the cell density is around 10^4/ml. We usually directly use cell lifters to scrape the the macrophages since the cells are very sticky to the plastic.
