Lab Note #3 The result

  Lab Note #3 The result Experiment date: 2020. 8. 31 Material: Microscope, cell counting machine, the result of the first experiment 1. Observing the result of the last experiment  Through a microscope, I observed colorectal cells that were treated with PLA2 and 5-FU. Then I took pictures of them through a computer connected to the microscope.  Though I expected to observe the reduced cells, I was surprised to see the cells that reduced only in a small amount. So I decided to use cell counting machine to get the exact result.  2. Counting cells Dead cells are stained red while alive cells are stained green. The machine then count the number of green cells and red cells.  First, I put small amount of buffer solution with chemical (PLA2 or 5FU) and cells on the small plate. (Pipetting should be done in order to make sure that cells aren't compacted together.) Then, I put the plate on the machine which starts counting. After I check the result, I saved it on the U...

Dormitory alone

     I throw myself on my bed being exhausted. I can hear my roommates under me talking loudly about food they are going to eat in home during weekends. Wishing the dormitory weekend menus to be good, I close my eyes for a short sleep until the first self study time begins.   Surprised with a large sound coming out from my alarm clock, I wake up. The total silence in a whole room makes me hard to believe that only 30 minutes have passed from the moment that the whole dormitory was full of sound of students being excited about going home. I consider sleeping for a whole self study for a moment, but I soon make up my mind and get out of the bed since I know dormitory teacher always look around the empty dormitory in order to check whether students cleaned their room before they leave.   I slowly put books in to study during the first self study time in my bag and go up to a cafeteria, my favorite place to study. A cafeteria which is usually full of students...
