Activation of caspase 3 in IECs undergoing anoikis. Cytosolic protein from IECs isolated by the four methods was analyzed by Western blotting for caspase 3. Uncleaved caspase 3 migrates at 32 kd. Activation of caspase 3 results in the appearance of the 30-, 20-, and 17-kd cleavage products. The control was provided with the antibody (32 kd). Letters below other lanes refer to the isolation method used.
