[Appropriate safety procedures should always be used with this material. Laboratory safety is discussed in the following publication: Biosafety in Microbiological and Biomedical Laboratories, 5th ed. HHS Publication No. (CDC) 93-8395. U.S. Department of Health and Human Services, Centers for Disease Control and Prevention. Washington DC: U.S. Government Printing Office (2007).

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. |

Once the feeder cells have attached, the culture medium can be changed to accommodate the cells to be supported. It is recommended that the feeder cells be plated 24 hours before use at 5 to 6 X 106/T75 in order to obtain a 100% confluent monolayer for stem cells growth.
These cells have been growth-arrested by irradiation with 6,000 rads. The cells will begin to deteriorate 2 weeks after plating and may no longer support the growth of other cells. We recommend that you do not keep the cells in culture for longer than 2 weeks.
