Method:PreparationofLymphoblastoidCellLinesforLongTermStorage
Method: Preparation of Lymphoblastoid Cell Lines for Long Term StorageMay 30, 1990Rosalie VeilePurpose:To store cell lines in a form that will insure recovery with high viability.A culture in logarithmic phase of growth with a total volume of 80-100 ml/T-75 flask should yield enough cells to freeze 10 ampules (1.0 ml/ampule). Cells should have a count of 4 X 106 cells/ampule to 9 X 106 cells/ampule. Too high or too l......阅读全文
