to enable comparisons from experiment to experiment, band densities for all products over a given gel were normalized to the band thickness for a sample from a dog subjected to sham procedure, treated with vehicle and killed 1 h after surgery. Each gel involved one or more sample from this type of control animal allow comparisons of data across different studies, and a control animal was purchase Enzalutamide prepared for each test. These antibodies were utilized in this study: 1) antiphospho Akt rabbit polyclonal antibody, which recognizes Akt only if phosphorylated at Ser473, 2) anti Akt rabbit polyclonal antibody, which recognizes total Akt, 3) anti phospho GSK 3B rabbit polyclonal antibody, which recognizes GSK 3B phosphorylated at Ser9, 4) anti GSK 3B mouse monoclonal antibody, which recognizes total GSK 3B, 5) antiphospho FOXO3A rabbit polyclonal antibody, which recognizes FOXO3A phosphorylated at Ser253, 6) anti FOXO3A rabbit polyclonal antibody, which recognizes total FOXO3A, 7) anti phospho MAPK mouse monoclonal antibody, which recognizes ERK1 and ERK2 phosphorylated on both at Thr202 and Tyr204 elements, anti MAPK1/2 rabbit polyclonal antibody, which recognizes total ERK1/ERK2, 9) anti W actin mouse monoclonal antibody, which recognizes an positioned within the N terminal domain of the B isoform of actin. Secondary antibodies for Westerns were horseradish peroxidaseconjugated Organism donkey anti rabbit IgG for polyclonal antibodies, or sheep anti mouse IgG for monoclonal antibodies. Caspase activity assays were performed on fresh frozen brain sections using the APO LOGIXTM carboxy fluorescein caspase discovery package according to the manufacturers directions. FAM DEVDFMK is really a fluorescein labeled analog of zDEVD fluoromethyl ketone, a wide spectrum cysteine protease inhibitor that enters cells and irreversibly binds activated caspases. FAM DEVD FMK exhibits greater affinity for caspase3 than for caspase 8, caspase 7, caspase 10 or caspase 6 and exhibits reduced affinity for the calpains than for caspases, ergo, at 5 uM FAM DEVDFMK can be a fairly selective inhibitor of caspase 3. More over, FAM DEVD FMK labeling of buy Clindamycin CA1 neurons fits nicely with caspase 3 activation, as assessed by Western blot analysis. In this study we therefore check with FAM DEVD FMK labeling as indicative of caspase 3 activity. In brief, estradiol and vehicleinjected animals were seriously anesthetized with pentobarbital and killed by decapitation at 2-4 h after ischemia or sham operation. Brains were removed, frozen and cut in to pieces in-the coronal plane of the dorsal hippocampus. Brain sections were washed 3 times with 1 Working Dilution Wash Buffer, labeled with 5 uM FAM DEVD FMK and seen under a ECLIPSE TE 300 fluorescent microscope equipped with a picture analysis program at an wavelength of 488 nm and emission wavelength of 565 nm.
