Figure 1From: Responsiveness of bovine cumulus-oocyte-complexes (COC) to porcine and recombinant human FSH, and the effect of COC quality on gonadotropin receptor and Cx43 marker gene mRNAs during maturation in vitroRepresentative 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.Back to article page
