Conditional Knockout iPS Cell Generation Service

Cell lines with a loss-of-function gene mutation is an invaluable tool for studying and understanding the function of genes and gene products. But a constitute knockout of an essential gene can affect cell viability and survivability. A conditional knockout cell line could rescue a potential lethality and give better control over the expression of the gene, as well as offer a more physiologically relevant model to study the role of the target gene and provide a target for drug discovery.

Service Advantages:

  • Optimized CRISPR protocols for high success rate
  • Homozygous/ heterozygous conditional knockout clones
  • Footprint-free, feeder-free transfection and iPSC culture protocols
  • Isogenic control lines for reliable experiments
  • Fully customizable

Standard Packaging:

Standard Deliverables:

  • Two (2) clones with confirmed modification(s), with two (2) vials of each clone at 1 x 10^6 cells/vial.
  • Project Milestones Reports, as well as a Final Report containing details of targeting design, experimental, and genotyping results.

Standard Workflow & Timeline:

  • Cell line evaluation
  • gRNA design, CRISPR vector, and donor DNA construction, and reagent validation
  • Transfection of targeting vectors and optimization
  • Screening for single-cell clones and clone confirmation
  • Cell expansion and cryopreservation

iPSC Genome Editing Service Workflow - Knockout iPS Cells

Timeline: 3-4 months

Required Starting Material & Information


  • Physiologically relevant disease models for hard-to-model diseases (Ex. ALS, muscular dystrophy, Parkinson's disease, Alzheimer's)
  • Differentiate to study mutations in different tissue lineages with an isogenic panel of cell line models
  • Ideal for target drug discovery, drug and toxicity screening
