I want to co-culture T cell and tumor cell to see T cell cytokines release. I used to co-culture them and add Golgiplug immediately for 6 hours. But now the cytokine signal is weak. Is it helpful to co-culture them more than 6 hours? Can I co-culture them without Golgiplug for maybe 12, 24 hours, and then add Golgiplug to keep cytokine in cells? Thank you
