How to use and characteristics of DNA flocking swab
The top of the DNA flock swab is a nylon fiber structure, and the nylon fibers are sequentially attached to the surface of the medical ABS plastic strip by an electrostatic field, and DNA is collected between the layers exactly parallel to each other and perpendicular to the surface of the internal rod.
What are the advantages of flocked swabs for DNA collection?
Sample collection process: The unique structure of the top of the flocked swab can greatly increase the number of samples collected.
Sample lysis process: the swab layer structure releases almost all collected samples.
Why is a flocked swab better for micro DNA collection?
The traditional cotton swab is an internal structure with twisted fibers at the top, which is dispersed by that fiber mass and left on the fibers during sampling, resulting in less efficient DNA precipitation of the original low content, which may even lead to false negative results of the test.
The tip of the flocked swab is a unique structure that allows almost complete extraction and precipitation of trace DNA, thus giving the flocked swab a more distinct advantage in collecting trace DNA.
Flocked swabs in the principle of DNA collection and precipitation?
(1) Cell samples can be completely captured by the directional friction effect of the swab's fiber layer.
(2) Since the cell sample is concentrated on the near surface of the swab fibers, about 95% or more of the sample can be eventually released.
(3) The capillary motion between the nylon fibers at the tip of the flocked swab creates a strong hydraulic pressure for absorbing liquid or cell-based samples.
How to use the DNA flocking swab
(1)Open the swab package first and take out the swab carefully, taking care not to touch anything before taking the sample to prevent contamination
(2) Place the swab on the area where the sample is needed, and take the sample by lagging, rotating or wiping
(3) Gently take out the swab, usually by placing the swab into the viral sample tube, breaking it where it is broken, throwing away the swab tail, tightening the cap and sending it off for examination as soon as possible.
