Pharyngeal, ear, nose, cervical, gynecological, male urethral DNA sampling swabs, DNA collection flock swabs, oral swabs, swabs
Flocked sampling swabs can be divided into pharyngeal swabs, oral swabs, DNA swabs, and cervical swabs according to different purposes, which can be used by various laboratory testing centers and hospitals.
Sampling flocked swab than the traditional winding swab collection sample and release sample volume is 3 times higher, and does not cause damage to the cell sample, good to ensure the survival rate of the cell sample, no residual fatty acids, the test detection effect does not cause impact, more will not cause harm to the human body.
Ltd. flocked sampling swab features.
① unique jet implanted nylon fiber technology to increase the collection and release of specimens.
② swab full length 14.5cm, with unique breakable design on the plastic rod.
③Fluffy texture allows collection of more target analytes.
④No specimen residual volume to speed up the specimen process
Ltd. disposable flocked sampling swab
In recent years, the use of oral swabs for DNA testing has gradually increased, because there is no domestic tool specifically for the collection of oral exfoliated cells, but only the use of ordinary medical swabs, and different people collect oral exfoliated cells in the number of wipes, strength, the amount of specimen cut and the amount of template used for amplification there are certain differences, resulting in the oral swab DNA preservation effect at room temperature is not very stable, affecting This has affected the application of oral swabs in DNA preservation at room temperature. In order to standardize the collection of oral swab DNA and improve the efficiency of oral swab DNA preservation, a method for prolonged oral swab DNA preservation and extraction at room temperature is urgently needed.
Package form: 100 sticks/box, 50 boxes/case
In view of this, the present invention provides a method for preserving and extracting DNA from oral swabs for a long time at room temperature that solves or partially solves the above problem.
To achieve the above technical solution, the technical solution of the present invention is: a method of preserving and extracting oral swab DNA for a long time at room temperature, comprising the following steps.
extraction method of oral swab DNA and the preparation method of preserving solution of oral swab DNA;
Product Description: The DNA extraction flocked swab produced by our company is made by nylon fiber flocking technology, the front end is coated with short nylon fibers fixed in a vertical manner, making the entire collection area of the swab collection area without absorption holes inside, DNA cells will not be dispersed and retained in the fibers, which is conducive to faster and more efficient elution. The product is equipped with the company's unique national patent preservation sleeve, swab suspended in the body of the tube, to prevent contamination of the test material due to packaging adhesion. The bottom of the tube is equipped with a special filter membrane to ensure air permeability inside and outside the tube to prevent mildew of the sample, while filtering out small particles of impurities in the external air that may affect the quality of the sample, which facilitates long-term storage of samples.
