Painless buccal DNA sampling

Human mouth cells, like other somatic cells, contain all genetic information of a human body. The cells can be collected by buccal swab using a cotton tip. Mouth cells and saliva absorbed to the cotton tip can be transferred to a piece of filter paper specially designed by Ningren. The filter paper can be sent to Ningren lab by regular mail. The collection of mouth cell is one of the most important steps for DNA analysis; you should carefully follow the procedure described below:

 

1 Please dont eat and drink 30 minutes prior to the DNA collection.

 

2 Open Ningren DNA Collecting Kit. Take out the cotton tip and the filter paper. Please be careful, dont let them be contaminated with any foreign substance.

 

3 Probe the cotton tip into mouth and rub it against inner cheek for about 30 seconds.

 

4 Place the soaked cotton tip on Sample Area of the filter paper. Press and turn the cotton tip lightly to transfer the saliva and cells onto the filter paper.

 

5 Put the filter on the surface of a clean table to air-dry it for about half hour, Put it into small sample pouch.
