Representative RT-PCR figures with gene on the left, PCR product size in bp on right. The leftmost lane is the 100-bp DNA marker lane (M) followed by oocyte quality grade 1, hour 0; quality grade 1, hour 6, etc. The negative lane (-ve) is the PCR blank which contains all components except cDNA. A second marker lane and positive tissue control (+ve) lane follow.
