Microinjections: ① Injection lines for site-specific integration: y sc v nanos-integrase; attP2 (the integrate site is on the 3rd chromosome) y sc v nanos-integrase; attP40 (the integrate site is on the 2nd chromosome) ② If you provide the DNA (20ug), please use Qiagen Mini Prep Kit to extract plasmid. ③ Vectors for site-specific integration: Vector name Integrate site Cell type Reference VALIUM1 attp2,on 3rd chromosome Somatic cells Ni et al., 2008, Nature Methods VALIUM10 attp2,on 3rd chromosome Somatic cells Ni et al., 2009, genetics. VALIUM20 attp2,on 3rd chromosome,or attp40,on 2nd chromosome Somatic and female germ line cells Ni et al., 2011, Nature Methods VALIUM22 attp2,on 3rd chromosome,or attp40,on 2nd chromosome Mainly for Female germ line cells Ni et al., 2011, Nature Methods These vectors can be used for protein overexpression as well. For p-element vector injection, please contact Luping Liu, email: lpliu@mail.tsinghua.edu.cn Tell: +86-10-62794230 ④ Cost: If you provide the DNA for injection, you will receive the transgenic fly about six weeks later, we charge 1500¥($240) per transgenetic line.
