Model Creation - CD BioSciences


Model Creation

Model Creation

A model organism is a non-human species (e.g. bacteria, animals, plants) that is used in a research lab to make scientific discoveries. Animals (e.g. mouse, rat, non-human primate) are the most widely used models, which are often genetically engineered. They are used in medical research to investigate human diseases or in basic research to study the function of genes. Advancing genome editing technologies like CRISPR/Cas9 allow for genome manipulation of animals to study the clinical signs or "phenotype" associated with certain genes.

Generation of bacterium/animal/plant models is time-consuming and complex, but inevitable for investigating the mechanisms of certain regulators in signaling pathways. As an experienced service provider for decades, CD BioSciences offers customized model creation services to help you obtain the best animal models resembling human diseases, or generate genetically engineered organisms of your interest.

Our Custom Services

Together with our Customized Gene Engineering service, we offer the following genome manipulation in model organisms.

Constitutive KO Whole-body knockout, permanently deactivating a target gene therefore the corresponding protein in the organism with CRISPR/Cas9 system.
Conditional KO
  • Tissue-specific KO
    (Spatially controlled knockout, deactivating a target gene in a certain tissue, with Cre/loxP system.)
  • Inducible KO
    (Temporally controlled knockout, deactivating a target gene at a given time-point in embryonic, post-natal or adult animals.)
  • Functional KO
    (Specifically mutating one or more nucleotides in a gene to cause loss of function of the target protein.)
Constitutive KI Adding a DNA sequence to an endogenous locus in the genome.
Point Mutation KI Specifically mutating one or more nucleotides in a gene to change the function of the target protein (gain/loss of function).
Reporter KI Inserting fluorescent, bioluminescent proteins or biochemical tags to a certain locus in the genome.
Humanization KI Substituting gene sequence in model organisms with the human counterpart.
Precisely controlling in vivo gene expression in organisms with RNA interference or inducible/reversible miRNA expression.
Designing and generating transgenic models to study transgene expression and function.
