Polysome profiling 원리
WebA few days before performing polysome profiling, prepare the sucrose gradient. Prepare 50, 35 and 20%sucrose solution and keep them at four degrees. Pour the 50%sucrose layer. Freeze it in a minus 40 freezer. After six hours, add the 35%layer and freeze it in a minus 40 freezer overnight. Pour the first 20%layer and freeze it. WebMar 18, 2024 · A successful polysome profiling should show clear 40S subunit, 60S subunit, 80S monosome, and several polysome peaks. The polysome peaks represent the RNAs bound to increasing number of ribosomes (>=2). The robustness of polysome peaks is dependent on the proliferation state of the cell samples and varies between different cell …
