- A Manton-Gaulin homogenizer is used for cell lysis. Which of the following are true? Increasing the number of passes can increase fine cell debris and make subsequent clarification more difficult. Cell growth conditions and phase of growth at which cells are processed can impact cell disruption. Decreasing temperature can increase protein release. Decreasing pressure reduces the number of passes required. Explain what is meant by the extent of cell disruption is 0.9.Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation(Salting Out) Egg whites contain about 88.5% water and about 10% proteins, from which ovalbumin is the major component. The eggs were cracked open, and the egg whites were separated carefully from the yolk. Stirring of the egg whites was done to break up the membrane. This was followed by filtration through cheesecloth, where a clear filtrate was obtained. About 40.0 mL of the filtered undiluted egg white was measured, and 0.10 mL of 1 M acetic acid was slowly added for every 1.0 mL of egg white with constant stirring. A turbid mixture with few amounts of white precipitate may be expected to form. These may be removed by filtering the mixture using a cheesecloth After filtration, 30.0 mL of the filtrate was obtained, and the solution was brought from 0% to 40% saturation by adding the required amount of powdered ammonium sulfate, (NH4)2SO4 After adding ammonium sulfate, the mixture was allowed to stand…Beginning with 10 grams of plant tissue, order the following procedures (as steps 1-4) that you will use to obtain a cell fraction that consists mostly of liquid cytosol and cell structures of very low density: collect pellet, collect supernatant, high-speed centrifugation for 15 min., low-speed centrifugation for 5 min, filter homogenate, grind plant tissue Step 1 collect pellet Step 2 low-speed centrifugatio Step 3 collect supernatant Step 4 high-speed centrifugatic v
