I'd like to find an alternative to Hek293T cells for retrovirus production. I understand that Hek293Ts contain the SV40 and large T antigen. Cos7 also contain these. Would this be a suitable cell type to make retrovirus? I appreciate your insight.

Any reason why you want to switch?
I have no experience with COS-7's so I can't really help you there.

This paper notes that Cos cells work better than Heks for retrovirus production. Also, I don't have access to Cos-1 cells right now, but the lab across from us is giving me some Cos-7s. But primarily, I'm unable to use Hek cells in experimentation due to it's origins.
