In the purest form, you only need to collect cells at a high density without contaminants and in 10% glycerol. We recommend starting from fresh 2 day old cultures, or collecting from a 2 day old plate. | In the purest form, you only need to collect cells at a high density without contaminants and in 10% glycerol.
