pMA7CR_2.0 expresses lambda Red and Cas9, which are separately inducible by L-arabinose and anhydrotetracycline (aTet), respectively. The Multiplex CRISPR/Cas9 Assembly System Kits enable construction of all-in-one CRISPR/Cas9 vectors expressing multiple gRNAs (2-7) and a Cas9 nuclease, nickase, dCas9, or dCas9-FokI fusion. A CRISPR/Cas9 toolkit for multiplex genome editing in plants. How can I track requests for my plasmids? What strain of bacteria does my stab contain? & Engineering, Model PubMed PMID 25997509. As with the Gersbach lab plasmids, multiple Cas9 variants are available: wt humanized Cas9, D10A nickase mutant (Cas9n), dCas9 (transcriptional repression), and Fok1-dCas9 (dimeric nuclease). Nakagawa Y, Sakuma T, Sakamoto T, Ohmuraya M, Nakagata N, Yamamoto T. BMC Biotechnol. Delivery options for Cpf1 multiplexing: Transfection, lentivirus, and AAV, was used to multiplex edit 3-4 genes in a primary culture of mouse neurons and, . Zetsche et al demonstrate this by showing that Cpf1 can cleave an array of 4 crRNAs in vitro and when expressed in 293 cells. pMAZ-SK contains an aTet-inducible gRNA and a backbone-targeting gRNA cassette for plasmid curing through "self-destruction" after induction with L-rhamnose and aTet.

Similar to a jigsaw puzzle, the oligos were designed with sticky ends that only anneal together in one direction. The pCRISPRiΔNp63A and pCRISPRiΔNp63A/B plasmids were constructed using a Multiplex CRISPR/Cas9 Assembly System Kit (Addgene, Cambridge, MA, USA; Kit #1000000055) and a Multiplex CRISPR dCas9/FokI-dCas9 Accessory Pack (Addgene, Kit # 1000000062) as previously described [ , ] with some modification.

For these experiments, cells were infected with a 1:1 ratio of two AAVs,  one expressing Cpf1 and the other a crRNA array plus a GFP tag.

Four weeks post-infection, there was strong expression of Cpf1 and GFP in the targeted brain region and ~75% of neurons were co-transduced with Cpf1 and GFP.

See the graph in figure 2 for a comparison of editing frequency resulting from transfection of single plasmids vs pooled plasmids; for multiple edits, single plasmids are generally more efficient. The CRMAGE system is a fast, multiplexable method that combines CRISPR and recombineering-based MAGE (Multiplex Automated Genome Engineering) technology.

5. One system you could use is pX333 from the Ventura lab. Although only wt hCas9 entry vectors are supplied with the kit, you can clone your own entry vectors containing other Cas9 variants to use with the MuLE system. This means Cpf1 can bind and cleave the lentiviral RNA, preventing packaging of the virus. Each destination vector contains GFP, enabling you to select cells with high GFP expression.

Sakuma, Tetsushi, et al. You also have the option of including a previously-designed tyr gRNA, which causes hypopigmentation, thus marking cells that have undergone genomic modification. Cpf1’s ability to process its own pre-crRNA arrays eliminates the need to include multiple promoters to drive crRNA expression and sequences that allow for array processing, i.e. pX333, a modification of pX330, contains humanized wtCas9 and two U6 promoters.

We archive and distribute high quality plasmids from your colleagues. Overall, these approaches have two main drawbacks: 1) Most rely on transfection of more than one vector to express the gRNAs and Cas9.

The first step in CRISPR/Cas9 Golden Gate multiplexing is to clone the oligonucleotides specifying each gRNA target sequence into distinct expression vectors using the enzyme BbsI. 1. Prior to this new Cpf1 multiplexing method, other multiplex CRISPR gene editing methods relied solely on Cas9. hbspt.cta._relativeUrls=true;hbspt.cta.load(306096, 'def26d9c-3f9c-4d7b-b065-3e0d0e24669b', {}); By expressing multiple gRNAs on the same plasmid, you’ll make sure that each cell that gets the plasmid contains all of the desired gRNAs. 1. In addition to the mammalian option described below, plasmids for making polycistronic gRNAs are also available from the Yang lab for use in plants. If Csy4 is not expressed, the gRNAs cannot be released, adding temporal and/or spatial control to the system. 96-well plate map for plasmid layout. A BsaI-based E. coli multiplexing plasmid is available from the Koffas lab.

Of these neurons, ~15% had indels at all 3 targeted loci. These plasmids can be used to express up to 8 gRNAs after Golden Gate or Gibson Assembly. For an in-depth review of Cpf1, check out this blog post or see Addgene's CRISPR guide page for a review of Cas9. It’s a simple and effective method with multiple applications (in vitro, in vivo, transfection, viral transduction) for simultaneous multi-gene editing with a single crRNA array. 2015 May 22;15(1):33. doi:10.1186/s12896-015-0144-x. This step is necessary to generate all of the overhangs needed for the final ligation step.

PubMed PMID: 25002478. 2014. Cpf1’s ability to process its own pre-crRNA arrays simplifies the crRNA cloning process.

This plasmid set allows you to express 2-4 gRNAs, with four being the ideal number. If you want to scale up the number of gRNAs in your plasmid, you’ll need to use some assembly methods such as Golden Gate or Gibson assembly.

Tsai, Shengdar Q., et al. Reversing the orientation of the direct repeat protects the (+) stranded lentivirus RNA from Cpf1-mediated cleavage.

There is a problem with the plasmid I received. 2013 Jan 3. Figure from Sakuma et al., Sci Rep . For cloning, Zetsche et al used four oligos that consist of direct repeats and crRNA. When these plasmids are digested, unique overhangs (here, O1-4) adjacent to the cut sites “link” fragments together and drive ordered assembly into a Cas9-containing destination vector.
