Stabilization of endogenous mutated c-Myc proteins in Burkitt's lymphoma cells.

Immunoblot analysis of c-Myc (upper panel), β-catenin (middle panel) and p27Kip1 (lower panel) after cycloheximide (CHX) treatment of Daudi, Raji, and CA46 Burkitt's lymphoma cells for the indicated time points was performed using specific antibodies as described in “Materials and Methods.”
