There are two ways to store it. One is air drying, and the other is using preservation solution. Let us take a look at how the first air drying preservation is done, and take a look at the specific process below.
Air dry preservation method:
Take the first cotton swab (wiping the head without touching the hand), stretch it into the oral cavity, and scrape it back and forth 20 times, close to the inside of the left cheek (rotate the cotton swab from time to time), and fully touch the oral mucosa. Take out the cotton swab and let it dry on white paper for 2 hours.
Take the second cotton swab and scrape it back and forth 20 times on the inside of your right mouth. Naturally dry for 2 hours; 4 Scrape the third cotton swab 15 times on the left and right sides, and dry naturally on the same white paper. Repeat to collect six copies.
Wrap it in white paper and put it in an envelope.
In repeating the above process, another person's oral mucosal epithelial cells were wrapped in white paper, and the symbol was clearly placed in another envelope. Note: Please do not mix cotton swabs! Please send it as soon as possible. In addition, don't just wrap plastic bags in paper.
