About 100 4 of the Euglena cells (volume) was
collected and suspended by adding 1 ml of ISOGEN II. 400 'al of
DEPC water was added thereto, and the mixture was vigorously
stirred for 15 seconds and allowed to stand at room temperature
for 15 minutes. After centrifugation (17,400xg, 4°C, 10 min) was
performed, 1 ml of the supernatant was collected from the
supernatant fraction, taking care not to take out portions near the precipitate. 1 ml of isopropanol was added thereto, and the
mixture was mixed by inversion and then allowed to stand at room
temperature for 10 minutes. After centrifugation (17,400xg, 4°C,
15 min), the supernatant was discarded, and 500 4 of 75% ethanol
was added to the precipitate, followed by centrifugation
(17,400xg, 4°C, 10 min). The precipitate was washed again with 75%
ethanol and subjected to centrifugation (17,400xg, 4°C, 5 min).
The supernatant was completely removed, and the precipitate was dissolved in 20 4 of DEPC water. The concentration of RNA was determined by measuring the A260 value with a spectrophotometer.

5. 7. 2 RT-PCR
For a reverse transcription reaction, SuperScript II
Reverse Transcriptase (Invitrogen) was used. RT-PCR was performed
using 5 vg of the total RNA.

Reverse transcription reaction solution 1 with the
composition shown in ตาราง 9 was used.
