I'm not an immunologist, so I welcome any comments or criticisms on this
attempt at an answer. The two methods I have seen for killing fibroblasts
1) culture medium with d-valine substituted for l-; fibroblasts lack the
enzyme to utilize the d- isomer. Available from Gibco.
2) anti-Thy1.1 followed by complement-mediated cell lysis. Don't know if
this would work in a hybridoma culture. Thy1.1 is a fibroblast-specific
cell surface marker. I can look up the antibody source if you want.
Am I the only person on earth who has killed fibroblasts? I forgot to add
pen/strep to a batch of DMEM/serum, but I bet that isn't the answer you're
looking for :-).
Reference to the above procedures (except forgetting pen/strep): Levison
and McCarthy, _Culturing Nerve Cells_ (Banker G and Goslin K, eds),
MIT Press, 1991 (I think).
Hope this helps
