The BP4 particles in the MARTINI force field prevent this process. This process is the first step in a technique that later adds a platinum “shadow”, then a thin coat of carbon to make a replica. Compounds that enhance stability when this process is performed are classified as “penetrating” if they cross cell membranes. In one technique, a sample is embedded in OCT compound, this process is performed, (-5[1])then a specialized (-5[1])microtome is used. One can study (15[1])lipid membranes by performing this process, then (*) fracturing the membrane (10[1])lengthwise to expose the interior. (10[1])Ethane is used (10[1])to perform a “flash” (10[1])version of this (10[1])process in a very high resolution form of electron (10[1])microscopy. (10[2])Biological tissues are mixed with ethylene glycol to prevent (10[1])damage caused by, for 10 points, what phase transition seen (0[1])in cryo-EM? ■END■ (10[1])
