hi, i am working on the cell culture of bipolar cells from rat retina too. i tried 3 times
and all i got was fragments of the cells. this is how i do it:
isolate retina
incubate retina with papain in hank's solution for 50min
wash retina 3 times with normal hank's solution ( i spin the retina, maybe i should not do it?)
tritrarate retina by pipetting up and down(about 15 times) (maybe too much?)
suspend cell in culture dish
i am going to try agian next week and hope me good luck作者: fei1226com 时间: 2012-6-8 16:51
It seem that you have treated the tisssue with trypsin too long. Over trypsinization will lead cell death and cell DNA release. The released DNA will make your digestion or cells clump. To solve the problem, you can 1) shorten the enzyme digestion time; or 2) add DNase at the last five minutes of enzyme digestion to degrade the released DNA. Let me know if you have further problem.作者: 中国特色 时间: 2012-6-8 17:08
