Custom CRISPR Multiplex sgRNA Vectors
Interested in knocking out multiple genes or recruiting transcriptional regulators using a combination of sgRNAs? abm’s CRISPR multiplex gRNA system allows for optimal expression of multiple gRNAs from alternating U6 and H1 RNA pol III promoters on a single lentiviral vector. gRNAs may be designed for use with any Cas9 variant, which is expressed from a separate vector (click here to see abm’s full list of Cas9-expressing vectors and viruses). Just tell us what you want to accomplish, and we’ll do the sgRNA design, cloning, and lentiviral packaging for you.

Applications
- Multi-target genomic mutagenesis:
- Target multiple sites at a single locus or target multiple different loci simultaneously
- Convenient for use with Cas9 nickase to increase specificity and reduce off-target effects. Easily co-express multiple gRNAs simultaneously.
- sgRNAs can be designed for use with any Cas9 (saCas9, spCas9, dCas9-SAM, dCas9-KRAB, etc.)
- Simultaneous activation, repression, knockout of multiple genomic targets:
- Activation using dCas9-SAM
- Repression using dCas9-KRAB
- Knockout using spCas9 or saCas9
* The vector for our CRISPR Multiplex sgRNA lentivectors is pLenti-Multi-gRNA-PGK-Neo.
Additional Information & MTA
Orders of this service are subjected to the completion of a signed Material Transfer Agreement (MTA) by the purchasing individual/institution for each order. If you have any questions regarding this, please contact us at technical@abmgood.com. The end user acknowledges that the Materials provided under abm’s MTA does not grant a license for commercial use or imply any ownership rights or any intellectual property rights relating to the Materials.
Please note that if the gene to be knocked out may be essential to cell survival, it is up to the end-user to proceed with the services. abm is unable to guarantee cell survival in these cases and will only attempt to rescue the clones under these conditions. abm is not accountable for cell survival if rescuing the clones (instructions to be provided customers) is unsuccessful. If customer chooses to proceed, abm will provide a hemizygous pool as the default deliverable to compensate for any lethal effects (unless otherwise requested).

FAQs
What promoter(s) do your sgRNA and All-in-One lentivectors have?
sgRNAs are expressed from the U6 promoter and All-in-One lentivectors and lentiviruses express Cas9 from the SFFV promoter.
What is the approximate time frame to generate CRISPR lentiviral constructs?
The typical lead time is around 1-3 weeks for CRISPR lentivectors and 4-6 weeks for lentiviruses. Please inquire for a more accurate lead time.
How should I store my lentivirus?
Aliquots should be made for the lentivirus and stored at -70 degrees Celsius.
If a high-titer custom lentivirus was ordered, do you do the lentiviral titration after a freeze-thaw or straight after production before the freeze-down step?
We do the titration after aliquoting and freeze-down. Thus, the titer should be accurate for the customer after they thaw the finished product for the first time.
Which virus has your lentivirus expression system been derived from? Is it HIV?
Our lentivirus expression system is derived from Human HIV-1 Virus. It employs third generation self-inactivating recombinant lentiviral vectors with enhanced biosafety features and minimal relation to wild-type Human HIV-1 Virus.
How do you verify the titer?
We use our LV900 series - qPCR Lentivirus Titration(Titer) Kit. This kit quantifies a proprietary region of the lentiviral 5’-LTR.
What is the packaging capacity for Lentivirus?
The maximum insert size is <9 kb between the 5'LTR to 3'LTR.
