Custom Overexpression Stable Cell Lines

The integration of exogenous plasmid DNA into the chromosome of host cells, followed by long-term expression of the target protein, is called a stable cell line. A high-quality stable cell line plays an essential role in biological research, including biosimilar development, gene function research and recombinant antibody production. However, constructing an effective cell line is a complex and time-consuming task. To simplify your experimental steps, KMD Bioscience is committed to improving the quality of our cell lines so that they can be used directly in your downstream biological research. Target cell lines constructed by KMD Bioscience are tested and trusted. We have successfully constructed a large number of target cell lines for many research clients. Based on advanced technology and dedicated research teams, KMD Bioscience can provide the following services:

 

CRISPR/Cas9 Knock-out Cell Line Services

IOS Overexpression Stable Cell Line Services

IOS RNAi Stable Cell Line Services

Pinpoint Targeted Integration Cell Line Services

 

IOS Overexpression Stable Cell Line Construction:

 

KMD Bioscience can provide gene overexpression stable cell line services based on our patented IOS (Integration Operating System) recombination technology. With this technology, the target gene was integrated into the genomic high-expression sites. These sites are safe (no gene) and also have higher gene expression levels (active expression sites), so that the target gene can be overexpressed and stably inherited for a long time. Moreover, gene integration is not limited in length, and multiple genes can be integrated simultaneously to achieve multi-gene co-expression.

 

The Principle of IOS Technology:

 

Step 1. Specific oligonucleotide sequences recognize target genes, open double strands and cause conformational changes.

Step 2. The patented RP protein specifically recognizes and binds to target sites, causing DNA damage, thus initiating DNA damage & repair mechanisms.

Step 3.  Dimer RP can pull foreign donor genes to the location of DNA damage, greatly improving the probability of recombination.
