Western blot analysis of C22orf29 in the following samples: Lane 1: human placenta tissue lysates, Lane 2: human A431 whole cell lysates, Lane 3: human HL-60 whole cell lysates, Lane 4: human U2OS whole cell lysates, Lane 5: human PC-3 whole cell lysates, Lane 6: rat lung tissue lysates, Lane 7: mouse HEPA1-6 whole cell lysates. Samples consisting of 50 µg (reducing conditions) of protein was separated with 5-20% SDS-PAGE gel (70V, Stacking gel; 90V, Resolving gel; 2-3 hrs.), transferred to a Nitrocellulose membrane (150mA, 50-90 min) and washed with TBS-0.1% Tween (3 times, 5 minutes/wash) and blocked with 5% Non-fat Milk/TBS (1.5 hrs., room temperature). The membrane was incubated in C22orf29 polyclonal antibody (Product # PA5-114405) at a dilution of 0.5 µg/mL (overnight, 4°C), followed by goat anti-rabbit IgG-HRP and chemiluminescence (ECL) with a dilution of 1:10,000 (1.5 hours, room temperature).
