Non-mammalian cells, including bacteria, fungi, and plant cells, have a cell wall that maintains the shape of the cell. These cell walls are particularly strong, due to their composition as they contain polymers that create a rigid sphere around the vulnerable cytoplasm contained inside the plasma membrane. In bacteria, the cell wall includes several layers…
One day, a colleague stopped by my workbench to ask which detergent would not break the nuclear membrane. Based on my previous experience using gentle detergents in lysis buffers, I replied, “NP-40”. However, we had two brands of NP-40. A closer look at the datasheets revealed that the chemical names were different even though they…
You’ve cultured your cells and completed your treatments, now it’s time to harvest them and proceed to the downstream effects. Cell lysis is the crucial stage that determines if your experiment has a chance of producing the data that you have been waiting for. Part of the starting biological material is inevitably lost on each…
