rAAV Packaging or Plasmid Instructions

  • Please apply proper enzyme digestion before sending out the plasmid. For example, the AAV plasmid must be digested with SmaI to ensure the integrity of the 5’ITR. The gene sequence length between ITRs should not exceed 4.7Kb.
  • The ITR region of the AAV vector plasmid is prone to mutations in the conventional DH5a strain at 37℃. It is recommended to culture and expand in Sure2 or Stbl3 strains at 30℃.
  • Please send via email the electronic file (gb or dna format) of the full map of the vector to us. When shipping the plasmid, you can drop 0.5 µg of the plasmid on a clean filter paper, outline the drop range with a pencil, and wrap it with plastic wrap to prevent contamination. With a volume greater than 10ul, put 5~10ug plasmids in a 0.5 mL centrifuge tube and wrap it with parafilm to ensure sealing.
  • The default final titer of customized product “high purity AAV” is ≧1E+13 GC/ml (unless special customer requires). Volume = total required amount ÷ actual titer.
  • The total amount of single-stranded fluorescent control virus is 10% of the total amount of expected customized AAV, and the titer is 1E+13 GC/ml.

Lentivirus Packaging or Plasmid Instruction

  • Please apply proper enzyme digestion before sending out the plasmid.
  • Since the Lentivirus vector plasmid is prone to mutations in the conventional DH5a strain at 37℃. It is recommended to culture and expand in Stbl3 strain at 30℃.
  • Please send via email the electronic file (gb or dna format) of the full map of the vector to us. When shipping the plasmid, you can drop 0.5 µg of the plasmid on a clean filter paper, outline the drop range with a pencil, and wrap it with plastic wrap to prevent contamination. With a volume greater than 10ul, put 5~10ug plasmids in a 0.5 mL centrifuge tube and wrap it with parafilm to ensure sealing. Vectors can be shipped in a buffered envelope at room temperature.

Plasmid Construction Instructions

  • For construction of overexpression vector, if there is a template plasmid, please provide 1μg plasmid and related map sequence information; If there is no template plasmid, please fill in the gene name, Gene ID or synthetic sequence, and select gene synthesis.
  • For sgRNA and shRNA, please provide the target sequence or target gene. If the target is not verified, it is recommended to select 2-3 more candidate targets.
