Cell Immortalization Service

Immortalized cell lines are cells that have been manipulated to proliferate indefinitely and can thus be cultured for long periods of time. They are either tumorous cells that do not stop dividing or cells that have been artificially manipulated to proliferate indefinitely and can, thus, be cultured over several generations to meet specific needs. KMD Bioscience has extensive research experience in cell immortalisation. We have already successfully constructed the immortalized cell lines derived from human, mouse and rat. Based on the dedicated scientific teams and advanced experimental platforms, KMD Bioscience has developed an efficient virus transfection technology. We offer a comprehensive range of reagents and engineered cell lines to meet your research needs. If you have any questions about production, please contact us. Our scientists will provide a reliable and risk-free immortalized cell line service to save your precious time and energy. We will escort your scientific research work!


Necessity of Cell Immortalization:


Although the primary cells have similar chromosome numbers as parent tissues and have specialized biochemical properties (growth factor and hormone secretion) as parent tissues, they have a limited lifespan/limited number of cell divisions, considerable variations in population and preparation, and are more susceptible to contamination. Cell immortalization could overcome those problems. Compared to primary cells, they tend to grow more quickly and can grow up to higher cell density, they are a uniform cell type, and most donor sources are the same therefore the batch-to-batch variation is less and they also maintain most cellular characteristics of the parent cells.  Using immortalized cell lines always saves money and time for long-term projects.
