Do you find that the domes spread a lot on the Nunclon Sphera plates? Do they remain attached for the entire 3-4 week culture period?

To avoid the spreading of the matrix and to have nice drop-like domes; it is crucial to preheat the plate for 2h at 37°C and to work fast when transferring the gel to the wells. Placing a warming plate under your laminar air flow hood when transferring the gel-cell-mix to the preheated plate may help. From our testing; we found that Nunclon Sphera wells were not ideal for our organoid system as the dome did not stay adhered; but it was able to move on the bottom and the dome became misshaped overtime. However; the altered shape of the dome did not affect the organoids and were successfully cultured for 4 weeks. If movement is not an issue for the user; we recommend that extra caution be taken during media changes by holding the plate at an angle and carefully pipette to remove old medium. Aspirating with vacuum suction can damage or destroy the dome.
