Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
(Note: The L-15 medium formulation was devised for use in a free gas exchange with atmospheric air. A CO2 and air mixture is detrimental to cells when using this medium for cultivation)
Cultures can be maintained by addition of fresh medium, or by collecting cells as a pellet after centrifugation. The packed cells are then resuspended in fresh medium. The initial inoculum should not be less than 2 to 3 x 105 viable cells/mL. A maximum of 1 to 2 x 106 cells/mL are obtainable. Do not aspirate suspension to break up clumped cells.
Medium Renewal: Add fresh medium (20% to 30% by volume) every 2 to 3 daysYosida TH, et al. Chromosomal alteration and development of tumors. XIX. Chromosome constitution of tumor cells in 16 plasma cell neoplasms of BALB/c mice. J. Natl. Cancer Inst. 41: 1083-1097, 1968. PubMed: 4176942
