A greatly simplified method of establishing B-lymphoblastoid cell lines

Ten lymphoblastoid cell lines were established by Epstein-Barr virus-induced transformation directly from 0.04 to 0.15 ml of peripheral whole blood of one patient with xeroderma pigmentosum and four normal healthy adults. All these lines expressed B-lymphocyte characteristics. The advantages of this method are: (a) only a few drops of blood are required for establishing a permanent line; (b) damage and loss of cells in separation procedures are minimal; and (c) the method is simple, reliable, and applicable, if desired, to any patient, even babies.
