| Abstract: | cDNA libraries from aborted human 3-month fetal brain,adult rat and mouse brain were constructed by using a yZAP express cDNA library construction kin.Low molecular weight fragments of the second strand cDNASA were removed by flowing through the Sepharose CL-4B column and the frractionated long,Middle,Short fragments and the combined fragments weire respectively inserted into clone vectors to construct the cDNA libraries of the brain of human 3-month fetus.The 5'ends of 1200 clones from each of human fetal brain cDNA libraries were sequenced.A total of 894 ESTs were obtained and some full-length clones were squenced.By andalyaing the se-quences,12 novel full-length cDNAs were obtained. |
