FIG. 9.

c-Myc is stabilized in Burkitt's lymphoma cell lines. EBV-immortalized B cells or the indicated Burkitt's lymphoma cell line were subjected to pulse-chase analysis as described in the legend to Fig. 1A, followed by immunoprecipitation of c-Myc with anti-MycFL. The half-lives were determined by a logarithmic analysis of the data obtained from densitometric scanning and the values shown are an average from two or more independent experiments. A representative pulse-chase experiment is shown.
