Thank you!

I would not recommend to grow RAW264.7 in RPMI because they will change in their metabolism and cell characteristics. https://uk.vwr.com/store/catalog/product.jsp?catalog_number=811-0067

You could try it but I am just warning you that the RPMI might change the cells. I would first compare cytokine expressions after 100ng/ml LPS using both media to be sure ;-)

Thank you Anouk!

It may be better to use bone marrow derived macrophages. I always used RPMI for them. The protocol is simple. Also you have the added advantage of numerous knockout mice at your disposal, and if that doesn't help, you can use RNAi. Raw cells are also on a Balb-c genetic background FYI.

Yes, i agree with Lynn Sonderegger, BMDM is a great option

You may try low-glucose DMEM + heated inactivate FBS.

 I've been using J774 in RPMI

Thanks to all!
