Immunoblot of caspase 3 of the lung extracts of guinea pigs exposed to air or CS given water or BT as the drink. Upper Panel: lane 1, air-exposed guinea pigs given water; lane 2, CS-exposed guinea pigs given water; lane 3, air-exposed guinea pigs given BT; lane 4, CS-exposed guinea pigs given BT. Activation of caspase 3 is evidenced by the formation of cleaved caspase (17 kDa product). Lower panel: the membrane was re-probed with anti-mouse tubulin antibody to determine the level of tubulin as a loading control.
