NOTICE that nowadays retroviruses are not the most frequently chosen viral vectors. Producer cells are commonly
stored frozen and thawing of the producer cells is followed by quality control testing and must be performed at almost
every order. For that reason both the scheduled delivery time and prices are 100€ higher than for lentiviruses.

Additional notes
1. For any additional information or comments please contact Naiara Tejados (send) who
will transfer any doubts and additional information requests to the production personnel.
2. SCALE OF PRODUCTION
Producer cells: GP2.293. Supernatant per P150 dish: 20 mL.
Mini-Retro: 1P100 SN. Batches cannot be concentrated by ultracentrifugation. Clarified
supernatant will be delivered. Vectors can be concentrated using PEG under request.
Midi-Retro: 1 P150 SN. Batches cannot be concentrated by ultracentrifugation. Clarified
supernatant will be delivered. Vectors can be concentrated using PEG under request.
Maxi-Retro: 3P150 SN. Vectors can be concentrated by ultracentrifugation under
request.
3. QUALITY of DNA.
Minimum purity values 260/280=1.8. RNA free. A photo of an EtBr or similarly stained
agarose gel will be required (attach as pdf or jpg format). Competent Stbl3 or similar, and
Endo-free DNA purification columns are strongly recommended.
DNA must be resuspended in H2O at 1 mg/mL. 30 micrograms of DNA are needed to
transfect one P150 dish.
4. TITRATION methods.
ALL the batches produced at VIVEbioTECH will be titrated and data delivered.
Depending on the specificities of vector titration will be done by default as follows:
 Whenever the transfer plasmid do encode for a fluorescent marker, ALL the
batches will be titrated by transduction of indicator HEK293T cell and FACS
analysis (included in the price). Fluorescent reporters´ absorption: 488–635 nm;
emission: 530-670 nm. For viruses bearing an antibiotic resistance gene inquire
for pricing.
Unit: transduction unit per mL (TU/mL)
Under request these batches can be also titrated by qRT-PCR (see below) with
an additional cost (see price)
 Whenever the transfer plasmid does not encode for a fluorescent reporter, ALL
the batches will be titrated by qRT-PCR on purified vector particles (included in
the price).
Unit: viral genomes per mL (vg/mL).
Regularly following our procedures 1T.U. is equal to 300-500 viral genome
containing particles.
Additionally, titration by integration events by qPCR on genomic DNA or by p24 ELISA
can be provided upon request with an additional cost (see price).
5. YIELDS.
Final yield depends on the size and specificities of the shuttle plasmid and transgen as
well.
Final titers are regularly >5x105 T.U./mL for non-concentrated batches and >5x107
T.U./mL for concentrated stocks.
IMPORTANT INFORMATION
1- All vectors delivered by the platform are for research use only.
2- The generated retrovectors need to be manipulated and used in BSL-II.

GENERAL CONDITIONS
1- Retroviral stocks will be dispatched before one month upon receipt of the transfer
plasmid under the conditions specified above. Any delay due to due to justified but
unforeseeable cause will be notified to the customer shortly after realization.
2- The customer´s material will be safeguarded for a six months period after the delivery of
the viral stocks. Thereafter it will be destroyed. Any incident regarding the quality,
damage or loss of the material along the storage at the PVV will be informed to the
customer and properly registered according to the Quality Guidance of the PVV.
3- VIVEbioTECH ensures the complete confidentiality along the whole process of both the
reagents and material from the customers´ side and the produced virus as well.
4- Production of retroviral vectors at VIVEbioTECH is based on the CLONTECH product
Retro-X Universal packaging Vector Set (Catalog No. 631457). We strongly encourage
the customers to please refer this product whenever data will be published or shared
5- VIVEbioTECH also acknowledges the indication of “VIVEBITECH SL“ as the
manufacturer’s source of the retrovirus employed in research projects.
