No special treatment is required to prepare a lysate for the active collection. The following procedure should be used for long-term storage of lambda clones in the archival collections. The phage are diluted in media containing 7% DMSO and frozen at -80 degrees C. - [Read Long Term Lambda Phage Storage Protocol]

Following propagation to 1 X 108 cells, lymphoblastoid cells are conveniently stored at -80 degrees C to preserve the high molecular weight DNA in the cells until the DNA is purified. This procedure describes the steps required to harvest and freeze the c - [Read Method: Preparation of Lymphocyte Cell Pellet for Storage]
