FuGU library services

Lentiviral services

Lentiviral services include amplifying DNA from in-house library or customer glycerol stock. HEK293ft cells produce lentiviruses after transfection of lentiviral DNA components. Viral titer measures capsid protein amount in viral prepation.



Can you prepare a custom lentivirus or retrovirus order?

Yes, customers are welcome to deliver their own retroviral or lentiviral constructs  (e.g. cDNA, shRNA etc.) to FuGU Libraries for custom viral particle production.

We collaborate with GBU cloning services for your lentiviral overexpression studies!
GBU does cloning from ORFeome and cDNA collections as well as from Gateway-compatible PCR products. 
Please contact for more details!

Production volumes

MINI scale produces 1,5 ml, MIDI scale 6 ml lentiviral medium and concentrated lentiviruses are in 180 or 360 microliters. Titer for lentiviral medium is 100 000 picograms and for concentrated viruses 1 000 000 picograms per milliliter.


Which quality controls are included?

Internal control is provided for all viral products.


Optional tests:

Capsid titer test (p24)*
Exclusion of replication competent virus (RCV test description here)*

* These analyses are for lentiviruses only. For retroviruses, quality control tests depend on the vector backbone and type (ecotropic or amphotropic pseudotypes).
