Custom Cell Lines

Horizon can tailor a custom cell line to your exact specifications

If you can't find your cell line of interest in our catalog, we can engineer a custom cell line for you. We use our cell line gene-editing platform to create a custom cell line to meet your exact specifications, whether that be a knockout, knockin, deletion, translocation or reporter cell line. Your custom cell line will be always delivered to you with its non-edited control.

Horizon’s team has 10 years of experience in genome-editing using CRISPR, rAAV and Zinc Finger Nuclease (ZFNs) technologies which allows us to complete complex gene-editing projects in agreed timelines. If we haven’t engineered the cell line of your interest yet, our cell line characterization and optimization service will be included to maximize success of your gene editing project.

*Knockouts by NHEJ-mediated frame-shift mutations. Defined deletions and gene disruption via targeted insertion are subject to knockin pricing. Some cell lines may be polyploid at some loci. Additional alleles may be modifed for an additional fee. **Possessed by Horizon or in ATCC for the commercial use. ***Characterization of more than one cell line is available for an additional fee. ¹Cell line must tolerate single cell cloning and display adequate transfection efficiency. ^{^}KI of additional alleles is available for an additional fee. ^#A plasmid donor carrying a selection cassette will be utilized.

Case studies

Case study I: CRISPR-Mediated Homozygous Knockout
Purpose: Disruption of the gene X in the human melanoma A375 cell line (copy number = 3)
Workflow Transfection with plasmids expressing Cas9 nuclease and a validated gRNA Derivation of single cell clones Screening of the clones Genotype analysis by Sanger sequencing	Targeting Strategy
Targeting Sequencing of individual alleles of 7 clones (via molecular cloning) demonstrated that 3 clones had out of frame deletions on all 3 alleles Sequencing of transcripts from individual alleles indicated out of frame deletions were also present at the RNA level for two of the three clones Clone 1
Case Study II: Heterozygous Knockin in Leukemia Cells
Purpose: To create a heterozygous point mutation K700E (AAA -> GAA) in SF3B1 in chronic myelogenous leukemia (CML) K562 cells using rAAV
Workflow Design of rAAV targeting vectors rAAV infection Plating of infected clones PCR and Sanger sequencing to identify KI pools Derivation of single cell clones Screening of the clones by PCR Genotype analysis by Sanger sequencing
Vector Design
Targeting Targeted allele-specific sequencing shows that both clones contain the K700E mutation. Non-allele specific sequencing shows a ratio of 50:50 of the mutant to wild-type peaks, as would be expected for a 2N locus.
