小中大大家怎么理解这句话：Lipofectamine™ 2000说明书上的：
4）incubate the cells at 37°C in a CO2 incubator for 24-48 hours until they are ready to assay for transgene expression. It is not necessary to remove the complexes or change the medium; however, growth medium may be replaced after 4-6 hours without loss of transfection activity.
是不是可以在24－48小时中换培养液？
