In my hands, I could get more cells using the protocol by Lutz et al and I found the procedure simpler using this protocol. I could get a similar purity with both protocols. Instead of using rGM-CSF, supernatant from J558L cells can be used at a 10-15% final concentration in culture medium
I have tried both the protocols and got very good purity of DC by Lutz protocol. You can try with rmGM CSF only and instead of 12 days we have minimized days upto 9-10 days.
