Customized Genetically Engineered Mouse Models

Combined with versatile technical platforms, GenoBioTX guarantees every custom model created is intended to fulfill diversified requirements from researchers. We offer not only classic knockout and knockin models, but also conditional point mutations and conditional knockouts with reporters. Our custom models will be the cornerstone of your research.

Comparison of Three Gene Modification Technologies

We provide one-stop animal model services aimed at accelerating translational studies of life science and medicine.

Technology Key Points Duration Applications Pros and Cons
CRISPR / Cas9 Cas9 nuclease cuts specific sites. 3-9 months Gene knockout,
conditional knockout,
gene knock-in, point mutation, humanization.
Pros – Short project cycle, high efficiency. Lower risk of off-target effects through sequencing verification. Successive generations can remove off-target sites.

Cons – Potential risk of off-target effects, but manageable by choosing appropriate sgRNA.
ESC Targeting Homologous recombination modifies genes. 9-12 months Gene knockout,
conditional knockout,
gene knock-in, point mutation, humanization.
Pros – Mature technology, stable results, no off-target effects. Can achieve large segment recombination.

Cons – Longer project duration.
PiggyBac Transposon Technology Transposon integrates
DNA segments into the
genome.
3-6 months Gene overexpression. Pros – Simple plamid insertion, high expression rate. Multiple insertion sites.
Cons – Subsequent experiments require establishing stable lines.
