Custom lenti viral packaging service

We use the third-generation lentivirus packaging system. Our lentivirus is pseudotyped with VSV-G. We titer lenti preps with Lenti-X™ qRT-PCR Titration Kit (TAKARA). Please provide at least 100 μg plasmid DNA for a lenti prep. Recommended DNA concentration is 0.5ug/ul~2ug/ul. DNA can be dissolved in sterile water. 

For lenti vectors with inserts < 7kb between two LTRs, we use ultracentrifugation to concentrate the virus. Final product is in 0.001%F68+DPBS. Typical yield is 150ul~200ul concentrated virus with genomic titer between e+11gc/ml~e+13gc/ml. Virus is good for both in-vivo and in-vitro applications. 

For lenti vectors with large inserts (7~10kb), we use lenti-X concentrator (TAKARA) to concentrate the virus. Yield is 800ul~900ul virus with genomic titer between e+8gc/ml~e+10gc/ml. Virus is only good for in-vitro applications.

As lenti viruses are not stable at 4 degree, we aliquot our lenti preps and store at -80 degree till pickup/shipment.

Custom AAV packaging service

We purify AAVs using iodixanol gradients and ultracentrifugation. We can package AAV vectors into serotypes 1, 2, 5, 6, 7, 8, 9, rh10, DJ, Anc80, SHH10, retro, 7m8, PHP.S, PHP.b, and PHP.eb. We titer AAVs with Sybr-Green based qPCR assays. Purified AAV is further filter sterilized by a 0.22um filter and is good for both in-vivo and in-vitro applications. Final AAV product is in 0.001%F68+DPBS.

We offer two scales of AAV production. For a regular scale AAV custom prep, typical yield is 250ul~400ul purified virus with genomic titer between e+12gc/ml~e+14gc/ml. Please provide at least 150ug verified plasmid DNA with DNA concentration between 0.5ug/ul~2ug/ul. 
For a half scale AAV custom prep, typical yield is 100~150ul purified virus with genomic titer between e+12gc/ml~e+14gc/ml. Please provide at least 80ug verified plasmid DNA with DNA concentration between 0.5ug/ul~2ug/ul.

Please make sure the insert between AAV two ITRs is less than 4.7kb. As ITRs might be lost during plasmid amplification, please make sure always digest your plasmid with SmaI after plasmid prep to confirm the ITRs are intact. You are supposed to see a 2.6~3kb backbone band. 

As AAVs are stable at 4 degree, we keep fresh AAV preps at 4 degree till pickup/shipment. For long term storage, please make aliquots and store at -80 degree.
