Unitat de Cell Immortalization
The Cell Immortalization Unit of the Josep Carreras Leukaemia Research Institute offers Infection of B-cells with Epstein–Barr virus (EBV) leads to more and subsequent immortalization. This is considered as the method of choice for generating lymphoblastoid cell lines (LCLs). Cell culture is an essential tool to study the fundamentals of genetic background variables. With the development of personalized medicine, this applies increasingly to the development and safety testing of drugs.
Infection of B-cells with Epstein–Barr virus (EBV) leads to more and subsequent immortalization. This is considered as the method of choice for generating lymphoblastoid cell lines (LCLs). Producing LCLs, although very useful but is very time consuming and troublesome, drives the requirement for quicker and more reliable methods for EBV-driven B-cell transformation.
The immortalized cells are derived from primary cells, thereby establishing an immortalized cell line to achieve the cells cultured in vitro. The purpose of unlimited proliferation and no difference between cells.
The primary cells only undergo a predetermined and limited number of cell division in the process of culture, however, after a limited population multiplication (the number varies according to species, cell types and culture conditions), the primary cells enter a state called replication aging, in which they no longer divide. So, scientists often need to recreate new cultures – a complex and lengthy process. Compared with primary cells, immortalized cells can solve this problem to a certain extent.
The exogenous immortalized genes were introduced into the target cells by gene transfection technology to establish immortalized cell lines, so as to make the cells cultured in vitro have the ability of proliferation and there is no difference between cells. Immortalized cells can be passed on continuously, enabling scientists to use the same consistent cells throughout the research project.
Summary protocol of Cell Immortalization Technology:
Peripheral Blood B Lymphocyte Immortalization with Epstein Barr Virus (EBV) Protocol
After successfully production of LCLs, different parameters including temperature, serum concentration, type of culture medium, and CO2 concentration have to be evaluated on EBV-transformed B-cells. Our unit are able to produce LCLs and optimize condition.
- This immortalization technology enables rapid, efficient, and reliable production of unlimited numbers of personalized cells.
- To produce control material for rare genetic disorders.
- Lymphocyte Immortalization technique let to preserve of DNA, RNA and proteins samples, that appears to be a valid strategy for further studies.
- To determine optimized condition for reliable and reproducible LCLs from different sources.
- Testing drugs analysis.
- Allows us to have enough biological sample without having to access the patient again.
EBV immortalized B lymphocyte cell lines have been extensively used as a source of biological material for functional and molecular studies and represent a potentially limitless source of genomic DNA, expression RNA, and protein and system biology analysis.
The Cell Immortalization Unit works closely with you in an integrated way beginning with the discussion of the project (including project outline and experimental design). we are continuously working to optimize the standard operation procedures and implementing the latest methodologies.
