Fig. 4.
Western blot analysis of the expression of Bcl-X, Bcl-2, Bax, Bad, and Bak in erythrocyte plasma membrane extracts.
Bcl-XL and Bak are expressed in terminally differentiated erythrocyte plasma membranes. As a positive control for the expression of these Bcl-2 family members, cell lysates were prepared from HL60 cells. Actin expression in erythrocyte membrane extracts is also shown as a control for the amount of erythrocyte protein present on the immunoblots.
