This protocol describes a method for testing of new serum lots prior to use in cell culture. Serum lots vary considerably in their ability to support cell growth, and some lots even contain toxic or growth-inhibitory compounds. It is advantageous to test serum lots and purchase in large volume, both for cost benefit. - [Read Serum Testing for Mammalian Cell Culture Protocol]
