因为不知道你们具体的做法,如果21天TEER只有500多,那细胞出问题的机会比较大.可能是细胞长的太慢,没有铺满(seed cell的数量?);或者细胞长的不够好,根本形成不了一块儿地毡.
以下是我们用的Procedure,希望有帮助.
Seeding of 24-well culture insert(day1)
*Pre-incubation of the BD transwell culture system:add 200ul of complete DMEM in each insert and 1ml in each well of 24-well plate.Incubate for 2hours at 37℃.
*Measure TEER in blank inserts before seeding.
*Seed 6x10^4 cells/cm^2 (2x10^4 cells/well) to each insert(in triplicate).
*Incubate the transwell culture system in the 37℃ CO2 incubator.
*Change medium for the transwell culture system every other day contiunously for 21-25days.
