摘要: 以莱茵衣藻CC-849 为材料,提取基因组DNA,利用BamH Ⅰ和Bgl Ⅱ对基因组DNA 进行酶解,获得了可用于构 建基因组文库的6-12 kb 的基因组片段,并浓缩至200 ng/μL。该片段与λDNA 载体连接,经噬菌体蛋白包装、侵染大肠杆菌XL1- blue 后,获得了莱茵衣藻基因组文库。该文库的滴度为2.12×105 pfu/mL,共有转化子4.26×104 个,插入片段的平均长度约为9 kb,扩增后基因组文库滴度为9.5×106 pfu/mL。

Abstract: The genomic DNA isolated from Chlamydomonas reinhardtii CC-849 was digested with BamH I and Bgl II. The 6-12 kb genomic DNA fragments were recovered from agarose gel and concentrated to 200 ng/μL. Then they were inserted into λDNA ZAP expression vector, packed by packaging extracts of λ phage and transformed into Escherichia coli XL1-Blue. Finally, the genomic DNA library was obtained with an average insert size of 9 kb. Results showed that the titer of genomic library was 2.12×105 pfu/mL and contained 4.26×104 clones. After amplified, the titer of genomic library was up to 9.5×106 pfu/mL.
