Precautions for preventing cell contamination

Precautions for preventing cell contamination

1. Before the experiment, the ultra-clean station was irradiated with ultraviolet light for 30-60 minutes, then the ultra-clean table top was wiped with 75% alcohol, and the ultra-clean table fan was turned on for about 10 minutes to start the experiment operation.
2. The laboratory supplies can be placed in the ultra-clean platform after being wiped with 75% alcohol; the laboratory supplies should be removed from the ultra-clean platform to facilitate the circulation of airflow. After the experiment is completed, wipe the clean bench top with 75% alcohol.
3. Only one cell is processed per operation; do not share the same bottle of media even if different cells use the same medium to avoid cross-contamination between cells.
4. Carefully take sterile items during handling to avoid contamination. Do not touch the tip of the straw, and replace it immediately after accidental touching; do not operate directly above the open container mouth. After the container is opened, tilt it 45°. After the operation is completed, close the cap.
5. The cleaning of the CO2 incubator is a relatively easy to ignore place. The incubator should be cleaned and disinfected regularly for 1-2 months. First wipe the inner wall of the incubator, baffle and water tray 2-3 times with 75% alcohol, wash with double distilled water, then wipe it again with alcohol cotton ball, and finally irradiate the UV lamp for more than 4h. Sterile water should be added to the water tray (replaceable every week), and the temperature, humidity and CO2 concentration in the incubator should be stabilized before being placed in the cells.
6. Regularly clean or replace the ultra-clean membrane filter and pre-filter.
