To begin, take a bottle of flies, transfer them into a new bottle every seven days in sync with their growth cycle. Collect the next generation of flies that hatch from the initial bottle three days after transferring, and place them into a fresh bottle. Next, place the glass tube into a large beaker.
Fill it with double distilled water and boil for 20 minutes. Then remove and bundle the glass tube. Rinse it three to five times with double distilled water, and place the glass tube in an oven to dry.
Using a pipette, add four milliliters of sample buffer and reserpine into a 10 milliliter small beaker. For the negative control group, add dimethyl sulfoxide until the concentration reaches 0.2%Carefully insert an appropriate length of glass tube into a small beaker to facilitate the flow of the medium. Wait for the culture medium to fully solidify.
Before removing the glass tube, wipe the outer wall to acquire a monitoring glass tube ensuring that one end contains the culture medium with drugs. Then heat solid paraffin in a beaker at 70 degrees Celsius until it melts. Immerse the glass tube's end in the liquid paraffin for about five millimeters and quickly remove it.
Wait for the paraffin to solidify to seal the food end of the glass tube. Put the anesthetized flies into paraffin sealed glass tubes and block the non-food end with an absorbent cotton ball. Load the tubes onto an infrared monitor to keep watch over them.
Align each tube so the infrared rays run vertically through the center of the flies active range. Set the monitor inside an incubator housed in the flies sleep darkroom.
