In recent years, CRISPR/Cas9 has become a powerful, precision tool to generate genetically engineered mouse or rat models with point mutation(s), small reporter gene insertions, conditional knockout or constitutive knockout. The CRISPR mouse models have paved a novel way for in vivo gene-gene interactions and phenotype association studies, for disease modeling, proof-of-concept gene and cell therapy studies, as well as for preclinical drug efficacy and safety studies.

Applied StemCell (ASC) is one of the first and most experienced provider of the CRISPR-Cas9 Technology. Our expert team of scientists have extensively researched and upgraded the CRISPR system to optimize the efficiency of Cas9 cutting, modification efficiency, and even improve birth rate of mice. With more than 11 years’ experience in mouse model genetic engineering, ASC is a leader in CRISPR mouse model generation service:

Generate a wide variety of mutations to fit your research’s specifications#:




CRISPR Knockout Mouse Models

Constitutive knockout of gene of interest either by frame shift mutation or targeted fragment deletion

  • Study main function of gene/ protein
  • Disease modeling
  • Validate gene function
  • Drug/ target discovery
  • Drug specificity

CRISPR Conditional Knockout (cKO) Mouse Models

Insert LoxP sites to flank gene of interest (floxed allele); the gene of interest is deleted when the cKO mouse is mated with an appropriate Cre-deleter mouse line* which expresses the Cre recombinase under control of a tissue-specific promoter or a mouse line where Cre expression can be induced at a specific developmental stage of the mouse.


The cKO mouse models can also be used to generate constitutive germline knockout mice when mated with a

mouse line expressing Cre under control of a ubiquitous promoter.

  • Study gene function in a specific tissue or specific developmental stage
  • Physiologically relevant disease modeling for late-onset or organ/ tissue-specific diseases
  • Overcomes problems such as embryonic lethality, developmental abnormalities and sterility, seen in germline deletion of critical genes1
  • One cKO mouse line enables comparison of gene function in several tissues using hundreds of commercially available Cre-deleter mouse lines*
  • Allows for better understanding of sporadic cancer development, cancer biology and translational oncology2,3

CRISPR Knock-in Mouse Models

Insert a gene of interest or target sequence at a specific genetic locus or a safe harbor locus


Reporter genes/ tags, gene/ promoter replacement; humanized gene knock-in; inducible/ conditional expression; gene overexpression mouse models

  • Study promoter regulation, gene expression, stimulus response
  • Modeling human genetics, biology or disease without mouse orthologues
  • Drug development and screening applications
  • Proof-of-concept gene and cell therapy studies
  • Preclinical drug efficacy and safety testing

CRISPR Point Mutation Mouse Models

Substitute one or more nucleotide in the targeted region to result in amino acid change.

  • Study role of nucleotides and amino acids gene and protein function(s) and regulation
  • Clinically relevant mutations for disease modeling
  • Pharmacogenomic screening with cancer relevant mutations
