Application
Gene knockout cells are an invaluable tool in molecular biology and genetics research. They have revolutionized our
understanding of gene functions by allowing scientists to investigate the effects of specific gene deletions or
mutations. These cells serve as valuable models to study gene function and reveal the impact of a particular gene on
cellular processes and organismal development.
Applications for gene knockout stable cell lines include:
- Studying gene functions: One of the main applications of knockout cells is to decipher the
function of genes of interest. By deleting the gene, researchers can evaluate its role in various biological
processes, such as cell division, differentiation or organismal development. This knowledge is critical to
understanding the underlying mechanisms of disease pathogenesis.
- Antibody specificity verification: To validate antibody specificity, gene knockout cells are
utilized to confirm the absence of signal in immunostaining or western blotting experiments. The knockouts are
generated by modifying the target gene within the cell's DNA using advanced techniques like CRISPR-Cas9 or
homologous recombination. After the removal of the target gene, the resulting cell line lacks the corresponding
protein on its surface or within its intracellular compartments. By comparing the staining or blotting results
with control cells that possess the target gene intact, they can determine if the antibody recognizes its
intended target accurately.
- Target validation and drug discovery: One of the key challenges in drug discovery is
identifying appropriate drug targets. Gene knockout cells can facilitate target validation to assess the
necessity of a specific gene as a therapeutic target. By deleting potential target genes, researchers can assess
the impact on cell viability or disease progression. This information can help identify promising drug targets
and develop effective treatment strategies.
- Establishment of disease models: Knockout cells can be used to model various genetic diseases.
By disabling specific disease-related genes, researchers can study how the loss or dysfunction of these genes
contributes to the development of the disease. This approach helps reveal the molecular mechanisms of many
genetic diseases, including cancer, neurodegenerative diseases, and cardiovascular diseases.
- Develop treatment tools: In the past few years, researchers have conducted a series of
gene-editing clinical trials, such as generating more effective CAR-T cells to treat cancer, and knocking out
the erythroid-specific enhancer of BCL11A to upregulate gamma globulin in autologous erythroid HSCs as a
potential treatment for sickle cell disease and beta-thalassemia. So far, there are already some cases of
ongoing clinical trials using the method of knocking out the PD-1 gene of autologous T cells to treat cancer,
including prostate cancer, esophageal cancer, and renal cell cancer. These trials are considered
proof-of-concept studies for applying in vitro CRISPR/Cas9 gene knockout technology to cancer treatment.
Case Study
Case Study 1
Excessive fibrosis underlies the dysfunction of many critical organs. Activated myofibroblasts accumulate within
pathological lesions in various fibrotic diseases, including patchy and interstitial fibrosis in progressive heart
failure and cardiac hypertrophy. Therefore, attenuation of myofibroblast differentiation is expected to alleviate
fibrosis. The researchers sought to find potential targets to mitigate fibroblast differentiation by analyzing
transcription factors in human fibroblasts/myofibroblasts, as fibroblasts undergo transcriptomic changes during
differentiation. Here, researchers report that a novel molecular target, transcription factor AP-2α (TFAP2A),
reduces fibroblast transdifferentiation.

differentiation. (The TFAP2A knockout cell line with NIH/3T3 fibroblasts (TFAP2A‐KO) was established using
CRISPR/CAS9 technology through Creative Biogene, Shirley, NY.) (Ross G R, et al. 2019,)
Case Study 2
Congenital anomalies of the kidney and urinary tract (CAKUT) are a diverse group of developmental defects that occur
in approximately 1:500 live births. In addition to its high morbidity, CAKUT is the most common cause of renal
failure in children. The study aimed to perform a miRNA-centric analysis to identify and functionally interpret
miRNAs most frequently affected by rare CNVs in CAKUT complemented by a CNV-centric analysis to estimate the overall
burden of rare CNVs on miRNA genes in CAKUT. Based on the functional interpretation, another aim of this study was
to experimentally confirm the impact of rare CNVs in CAKUT on candidate miRNA expression and subsequent changes in
the mRNA levels of selected target genes.

FAQ
Q: What is a knockout cell?
A: A knockout cell refers to a type of genetically modified cell used in research to understand the
function of specific genes or proteins. In a knockout cell, a specific gene or protein is intentionally
deactivated, or "knocked out," through techniques like gene editing or gene disruption.
Q: What is the difference between knockdown and knockout cells?
A: Gene knockout refers to the complete elimination of a gene from an organism. Gene knockdown refers to
the reduction of gene expression in an organism. It can only be achieved through genetic engineering
technology. It can occur through chemical agents or genetic modification.
Q: How are your knockout cell lines generated?
A: Our knockout cell lines were generated using CRISPR/Cas9 technology. knockout cell lines were
monoclonal and verified using Sanger sequencing.
Q: Do you test your knockout cell lines for mycoplasma?
A: Yes, the cell line bank is tested for mycoplasma. In addition, we conduct regular spot checks of our
inventory.
Q: What is the biosafety level (BSL) of your cells?
A: Our knockout cell lines are divided into BSL1 and BSL2 based on cell line. Cell lines such as A549,
HCT116, HEPG2, and MCF7 belong to BSL1. HEK-293T and HeLa cell lines are BSL2.
