[Human B-lymphoblastoid cell lines: optimal conditions for their procurement, selection, cultivation and cloning].

The protocol of Epstein-Barr virus (EBV)-induced transformation of B-lymphocytes from reripheral blood of normal humans has been described. The requirements for mononuclear EBV-infection and for selection, cultivation, and cloning of EBV-transformed cell lines have been investigated. Successful establishment of stable human immunoglobulin-producing cell lines from lymphocytes of immunized donors could be achieved following the protocol presented.
