The lch-1 primer pair, 5′-TCCAGCTCCAAGAGGTTTTTCAG-3′ and 5′-GTCCCTTTGAGGCAGGCATAG-3′, generated a 250-bp product. The Mch2α primer pair, 5′-CTGTTAGCCACGCAGATGCC-3′ and 5′-TGTTCACCAGTGTGAGGAGTTCTG-3′, generated a 447-bp product. The Mch3 primer pair, 5′-GCTGAGAAGCAATGGGTCACTC-3′ and 5′-TGCAGTGG ACACAGCCATGAG-3′, generated a 300-bp product. The glyceraldehyde phosphate dehydrogenase (GAPDH) primer pair, 5′-CCATGGAGAAGGCTGGGGC-3′ and 5′-CCAAAGTTGTCATGGATGTCC-3′, generated a 195-bp product. All products were analyzed by 1.0% agarose gel electrophoresis.

    • 6 per 10-cm plate) were washed twice with ice-cold phosphate-buffered saline (PBS), scraped into PBS (1 ml), and sedimented in a microcentrifuge for 30 s at 4°C. The supernatant solution was removed, and the sedimented material was resuspended in 100 μl of lysis buffer (PBS, 0.1% phenylmethanesulfonylfluoride, 1% NP-40, 0.5% sodium deoxycholate, 0.1% SDS) and incubated on ice for 20 min. The extracts were sedimented in a microcentrifuge for 30 min at 4°C. The supernatant solution represented whole-cell extract; 100 μg of this protein was analyzed by SDS-polyacrylamide gel electrophoresis (10% gel) and subsequently transferred to a polyvinylidine difluoride membrane for 12 hours at 4°C. The membrane was incubated for 12 hours in 5% blotto {5% Carnation milk in 1 × tris-buffered saline (TBS) [10 mM tris-HCI (pH 8.0) and 150 mM NaCl]}. Monoclonal antibodies to lch-1, Cpp32, and Fas (Signal Transduction Laboratories) were added to separate transfers at 1:1000 dilutions, and a polyclonal rabbit antiserum to Ice (Santa Cruz Biotech, Santa Cruz, CA) was added at 1 μg/ml. After incubation at room temperature for 2 hours, tne transfers were washed three times with 1 × TBS for a total of 30 min. Secondary antibodies were incubated with the transfers at 1:1000 dilutions for 1 hour at room temperature. The transfers were washed four times with 1 × TBS for a total of 1 hour and analyzed by enhanced chemiluminescence using Pierce reagents, followed by exposure to x-ray film.
