| Is there an MTA available for the cell line? | Yes |
| For generation of the cell line, who was the supplier of any recombined DNA vectors or commercial kits used? | Vectors were generated at IDR, pU6-(BbsI)-sgRNA-CAG-Cas9-Venus-bpA plasmid (Addgene plasmid #86986) was used. |
| Are you aware of any constraints on the use or distribution of the cell line from the owner or any parties identified in the query above? | Yes |
| Constraints for use or distribution | According to donor consent the line must not be used for commercial purposes. For research purposes project-specific review by a medical Ethics Committee is obligatory. |
hIPSC Derivation
General |
|
|
The source cell information can be found in the parental cell line
HMGUi001-A.
|
|
| Passage number reprogrammed | 26 |
Reprogramming method |
|
| Vector type | Non-integrating |
| Vector | The CCKBR locus was targeted by homologous recombination and CRISPR/Cas9 technology using histone 2B (H2B)-Venus-3xHA-tag targeting vector. We cloned the sequence of the (H2B)-Venus-3xHA-tag into a targeting vector and used the 897 bp upstream and 833 bp downstream of the CCKBR start and stop codon respectively as 5′ and 3′ homology arms (HA). A pair of gRNAs introducing dsDNA breaks 8 bp downstream of the start codon and 2 bp upstream of the stop codon of CCKBR were cloned into the pu6-sgRNA-CAG-Cas9-VenusbpA expression vector. |
| Is reprogramming vector detectable? |
Yes |
