What are the flocking sampling swabs and their uses





Flocking sampling swabs can be divided into throat swabs, oral swabs, DNA swabs, and cervical swabs according to different uses, which can be used by various laboratory testing centers and hospitals. The sampling and flocking swabs are 3 times higher than the traditional wrapping swabs to collect and release samples, and do not cause damage to the cell samples. It will not cause harm to the human body.


Flocking Sampling Swab Features:


①The unique jet implantation nylon fiber technology increases the collection and release of specimens. ②The total length of the swab is 14.5cm, and the plastic rod has a unique breakable design. ③ The fluffy texture can collect more target analytes. ④ There is no residual specimen, which speeds up the specimen process


Disposable flocked sampling swab


In recent years, the use of oral swabs for DNA testing has gradually increased. Since there is no tool for collecting oral exfoliated cells in China, only ordinary medical cotton swabs are used, and different people collect oral exfoliated cells. There are certain differences in the amount of sample clipping and the amount of template used for amplification, which leads to the unstable preservation effect of oral swab DNA at room temperature, which affects the application of oral swab in DNA preservation at room temperature. In order to standardize the collection of oral swab DNA and improve the DNA preservation efficiency of oral swabs, a method for long-term preservation and extraction of oral swab DNA at room temperature is urgently needed.


Packing form: 100 pcs/box, 50 boxes/carton


In view of this, the present invention provides a method for preserving and extracting DNA from oral swabs at room temperature for a long time, which solves or partially solves the above problems.


In order to achieve the effect of the above technical solution, the technical solution of the present invention is: a long-term oral swab DNA preservation and extraction method at normal temperature, comprising the following steps:


Extraction method of buccal swab DNA and preparation method of buccal swab DNA preservation solution;


Product introduction:


The DNA extraction flocking swabs produced by our company are made of nylon fiber flocking technology. The front end is coated with nylon short fibers fixed in a vertical manner, so that there are no absorption holes in the entire collection swab collection area, and DNA cells will not be scattered. Retained in fibers for faster and more efficient elution. The product is equipped with the company's unique national patent preservation sleeve, and the swab is suspended in the tube to prevent the test material from being contaminated due to packaging adhesion. The bottom of the tube is equipped with a special filter membrane to ensure the air permeability inside and outside the tube, prevent mildew of the test material, and filter out small particles of impurities in the external air that may affect the quality of the test material, which is convenient for long-term storage of samples.
