It can also for throat sampling of respiratory viruses such as influenza, swine flu, avian flu, hand, foot and mouth.

The principle of flocking swab in DNA collection and precipitation

1.Through the directional friction effect of the swab fiber layer, the cell sample can be completely captur.

2.Since the cell samples are concentrat near the surface of the swab fiber, more than 95% of the sample can be released eventually.

3.The capillary movement between the nylon fibers on the top of the flocking swab generates a powerful hydraulic pressure to absorb liquid or cell samples.

What are the advantages of flocking swabs for DNA collection?

2.Sample dissolution process: The sample collect by the swab is basically located on the surface of the swab. Therefore 95% of the sample can be releas, which can be regard as almost all samples can be wash off.

Why flocking swabs are more beneficial for micro-DNA collection

1.The top of the traditional cotton swab is make of cotton fiber entangl internal structure. When sampling, the fiber clusters will be scatter and retain on the fibers. As a result, the precipitation efficiency of the original low-content DNA is reduc.

2.The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA. Therefore, the flocking swab has a more obvious advantage in collecting trace DNA.
