Process Guidelines
CRISPR Module 1: Background Study and gRNA Design
In this module, which takes about two weeks to complete, the iPS Core consults with the investigator to develop a targeting strategy for the generation of an edited human pluripotent stem cell (hPSC) line.
This module delivers customized design of CRISPR guide RNAs complementary to the DNA sequence in the genomic site to be targeted.
CRISPR Module 2: CRISPR-mediated KO relying on indel to create frameshift
In this module, which takes about 8-12 weeks to complete, the iPS Core targets a human pluripotent stem cell (hPSC) line to produce a frameshift mutation in a protein-coding gene, usually targeted to trigger decay of the mRNA transcript.
Service steps include transfection of one hPSC line with CRISPR guide RNA and Cas9 (Neon system: 3 voltages), analysis and subcloning of the transfected cell pool, screening of 96 clones, analysis and expansion of clones with desired genotypes, cryopreservation, and QC consisting of thaw testing, mycoplasma testing and sequence confirmation of the edited locus.
This module delivers cryopreserved stocks for four clones with desired genotypes; typically two knock-out and two non-targeted control clones.
CRISPR Module 3: CRISPR-mediated KI using ssODN
In this module, which takes about 8-12 weeks to complete, the iPS Core targets an hPSC line to modify a genomic sequence using a short template encoded in a single-stranded oligo DNA nucleotide (ssODN).
Examples include modifying a single nucleotide polymorphism (SNP) or inserting a short sequence <50 nt in length.
Service steps include transfection of one hPSC line with CRISPR guide RNA, Cas9 and ssODN; analysis and subcloning of the transfected cell pool, screening of 96 clones, analysis and expansion of clones with desired genotypes, cryopreservation, and QC consisting of thaw testing, mycoplasma testing and sequence confirmation of the edited locus.
This module delivers cryopreserved stocks for four clones with desired genotypes; typically two knock-in and two non-targeted control clones.
CRISPR Module 4: CRISPR-mediated transgene insertion with selection cassette
In this module, which takes about 8-12 weeks to complete, the iPS Core targets an hPSC line to insert a transgenic sequence >50 nt in length that includes a selection marker. The investigator provides a plasmid that encodes the transgenic sequence and homology arms corresponding to the desired insertion site.
Examples include the generation of reporter lines.
Service steps include transfection of one hPSC line with CRISPR guide RNA, Cas9 and plasmid; antibiotic selection of the transfected cell pools, analysis and expansion of clones with desired transgene insertion, cryopreservation and sequence confirmation of the edited locus. If selection cassette removal (Module 5) is not chosen, service steps of Module 4 will also include thaw testing and mycoplasma testing.
This module delivers cryopreserved stocks for two clones with desired transgene insertion.
CRISPR Module 5: Selection cassette removal with Cre-LoxP, PiggyBac or FLP-FRT
In this module, which takes about 4-6 weeks to complete, the iPS Core removes a cassette from an hPSC line using Cre recombinase, PiggyBac transposase or FLP recombinase.
Service steps include transfection of one hPSC line; subcloning of the transfected cell pool, analysis and expansion of clones with the selection cassette removed, cryopreservation, and QC consisting of thaw testing, mycoplasma testing and sequence confirmation of the edited locus.
This module delivers cryopreserved stocks for two clones with desired transgene removal.
