I bought a new water glue containing rgd, but on the second day of fluorescent dyeing (when I picked up the water glue from the wet bed and used PBSt wash), I was sure that it was a complete piece when I picked it up from the wet bed. dish, but when I was about to wash it for the first time (tween20+pbs), all 8 dishes of hydrogel disappeared (not even the hydrogel block was left). I went to the microscope to see that all the cells were floating in the dish. I would like to ask if you have any ideas?
