Freeze lysis
WebFreeze-thaw lysis is pretty much as it sounds, using liquid nitrogen or a freezer to freeze the cells and then allow them to thaw. When cells are frozen the water inside the cells expands as it freezes causing the cells to burst open. This method is effective for mammalian cells. WebThe Qiagen miRNeasy micro kit protocol suggests to thaw frozen lysates by incubating at 37C to allow salts to completely dissolve. However, prolonged incubation at 37C can …
