Array CGH comparison of genomic sequence content between tissues from the same animal

DNA was isolated from tissues (blood, sperm, or liver). DNA from different tissues from the same organism were labeled with alternate fluorophores (Cy3 or Cy5) and hybridized to a custom array that was designed from lamprey (Petromyzon marinus) genomic sequence. 1 animal - sperm vs. blood, 2 animals - blood vs. liver

从血液、精子或肝脏等组织中提取脱氧核糖核酸（DNA）。将同一生物体不同组织的DNA分别以Cy3或Cy5荧光基团标记后，与基于七鳃鳗（Petromyzon marinus）基因组序列定制的基因微阵列进行杂交。实验分组设置为：1头动物，对比精子与血液组织的DNA；2头动物，对比血液与肝脏组织的DNA。
