How can DNA be extracted from saliva?
it is quite a tricky one to do.
There is a more conventional method called the proteinase K-saline precipitation protocol. To learn more about it, watch this video: https://tutor.hix.ai This method involves substituting saliva for the mouse tail.
take a person's saliva.
Add 30 MU of Proteinase K and 720 MU of STE.
I should point out that the majority of the isolation is done with a kit; an example of one is provided below.
There are numerous papers on commercial methods that claim to be able to isolate up to 110 micrograms of genomic DNA with very little sample required. One such method involves combining the prepIT•L2Pextraction kit with the Oragene kit.
The protocols' specifics are listed below.
take a person's saliva.
Store it in the Oragene kit (which needs liquid saliva without bubbles).
Gather the supernatant.
After adding 600 ml of 95% ethanol and stirring the mixture, leave it to stand at room temperature for ten minutes.

DNA can be extracted from saliva using various methods, but a common approach involves the following steps:
- Collect the saliva sample from the individual.
- Mix the saliva sample with a solution containing a detergent to break down cell membranes and release the DNA.
- Add a protease enzyme to break down proteins and remove them from the sample.
- Add a salt solution to precipitate the DNA, causing it to separate from other cellular components.
- Centrifuge the mixture to separate the DNA from the rest of the solution.
- Remove the supernatant and wash the DNA pellet with ethanol.
- Finally, dissolve the DNA pellet in a suitable buffer solution for further analysis or storage.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
