Generation of lymphoblastoid cell lines (LCLs) by EBV transformation from separated frozen whole blood, and from PBLs

Lymphoblastoid cell lines (LCLs) are generated by Epstein-Barr Virus (EBV) transformation of the B-lymphocyte component within the peripheral blood lymphocyte (PBL) population. Once a cell line has been successfully established, a bank of four ampoules is generated and stored in our cryostorage facility. 

Sample progress is tracked using a purpose built Laboratory Information Management system, linked to electronic inventory management software. As part of routine quality assurance, all cell banks are screened for freedom from mycoplasma, and a proportion of every batch is tested for sterility, cell count and viability and authenticity against source material (blood spot card prepared at receipt) using STR-PCR profiling. 

The process takes approximately five to six weeks to complete. As part of the service, frozen cells or a growing culture (if requested at the time of transformation) can be returned to the customer. A start-up fee will be charged for growing cultures requested at a later date. 

 
We have the capacity to initiate up to 1000 scheduled EBV transformations per month, the overwhelming majority of which are from frozen PBLs resuscitated from liquid nitrogen storage, and we aim to achieve a transformation success rate of at least 95% at first attempt.
