The sample will be placed into a mortar (be sure to get it the sticky plaque off of the toothpick). 2. Dispense 2 ml of the buffer into the mortar and grind the buffer-plaque with the pestle. Grind it up well. 3. You will make a 1/100 dilution (as near as we can, considering that we will not weigh out the plaque) of the plaque in phosphate buffer by adding the ground up plaque-buffer in the mortar back into the 99ml diluent buffer bottle and mixing it well . 4. Make 10 fold dilutions by using 9ml phosphate buffer solution dilutions. Be SURE to mix each dilution well, and use new pipettes. o Transfer 1ml of the 10-2 into 9ml phosphate buffer, using a fresh pipette: This is a 10 -3 . o Transfer 1ml of the 10-3 into 9ml phosphate buffer, using a fresh pipette: This is a 10-4. o Transfer 1ml of the 10-4 into 9ml phosphate buffer, using a fresh pipette: This is a 10-5. o Transfer 1ml of the 10-5 into…
