Bcl2 expression in T-ALL cell lines. Western blotting analyses for the basal expression of Bcl2 in untreated T-ALL cell lines. Twenty micrograms of protein was blotted to each lane. Antibody to β-actin served as a loading control. Molecular weights are indicated on the right. Densitometric analysis was performed using a Chemidoc 810 Imager with the appropriate software (UVP, Upland, CA, USA), and for each cell line, Bcl2 protein expression is indicated relatively to β-actin expression
