Virus Sampling Kit is a virus sampling kit consisting of a storage tube (with virus sample storage solution), a sampling swab and a biological bag. Virus sampling tube which is suitable for nucleic acid extraction and subsequent virus isolation of influenza virus, avian influenza virus, coronavirus, hand, foot and mouth virus, measles virus and other virus samples. It is also suitable for the collection and transportation of specimens such as chlamydia and mycoplasma. Samples are usually collected from the mouth, throat, nasopharynx and other parts of the body.
Which is the best virus sampling tube: flocked cotton swabs are recommended (polyester cotton tips are also acceptable).
Virus sampling tube which is good: the tube body and cap are made of medical polypropylene, resistant to high temperature (121°C), low temperature (-80°C), static extrusion and dynamic impact. Conical bottom design resists centrifugation and vibration. Built-in sample retention solution is used to release and preserve the sample and prevent leakage. Built-in glass beads help with sample elution. Divided into 10ml, 7ml and 5ml depending on the volume of the sampling tube.
Classification of sample preservation solution.
Inactivated: Built-in 2-3ml UTM solution and clear pink solution, suitable for virus preservation solution formulation, which can maintain virus activity in a wide temperature range and preserve the original sample as much as possible. It does not contain lysates, maintains the activity and integrity of the pathogen, and can be used for virus culture and isolation.
Inactivation type: Built-in 1-3 ml of preservation solution with or without guanidine salts as needed. Sample preservation solution with guanidine salt: mixture of virus lysate and nucleic acid preservation solution, colorless and transparent, or light red transparent liquid, customizable. The product can instantly lyse pathogens to release nucleic acid, and the protective solution can prevent nucleic acid from being degraded, effectively ensuring the integrity of viral nucleic acid in the sample, and the collected sample can be transported at room temperature and stored for a long time.
Guanidine salt-free sample preservation solution: contains special protein denaturant and nucleic acid stabilizer; protein denaturant can quickly destroy the secondary structure of the virus shell protein and inactivate the virus, while nucleic acid stabilizer can be preserved at room temperature without degradation, avoiding the degradation of nucleic acid in the sample before detection, resulting in "false negative" Nucleic acid testing.
Biosafety Bags: Sampling tubes containing viral samples are stored and transported in biobags. Health medicine is the standard for medical screening.
Virus sampling tube which is good: This virus sampling kit is packed in international paper or blister, sterilized and sterile.
Virus sampling tube which is good, not only is it versatile, but also has product advantages. On the outside, it uses plant fleece. The fluffy white hair is soft and suitable for different people. Taken together, this planning is simply broken and easy to use.
The plastic stick is designed to break easily for sample transport. It is important to use disposable sterile packaging, radiation sterilization, and individual packaging. So what kind of virus sampling tube should be used?
1. Samples are collected using sampling swabs according to sampling requirements (preservation solution without swabs, users can provide their own matching swabs).
2. After the virus sampling tube collects the sample, place the sampling swab.
3. Break the swab at the easy break point of the sampling swab, discard the tail, and close the tube cap.
4. Label the sampling tube with information as needed.
5. Collected specimens should be transported to the appropriate influenza surveillance network laboratory within 2 working days at 2-8°C; if delivery to the laboratory is not possible within 48 hours, set to 70°C or below for storage and ensure that collected specimens are delivered to the appropriate network laboratory within 1 week. Repeated freeze-thawing of specimens should be avoided.
6. For nasal swabs, the collector holds the patient's mandible with the left hand, then gently inserts the swab into the nasal palate of the nasal tract with the right hand, stays for a few moments, and then slowly rotates 3-5 times before withdrawing. Wipe the other side with another swab. Dip the swab head into the sampling solution, squeeze the swab head in the sampling solution several times, break the end of the swab firmly and discard the end of the swab.
7. Press the patient's tongue with the throat swab with the left hand. Swab the bilateral pharyngeal tonsils and posterior pharyngeal wall with the right hand swab, dip the tip of the swab into the sampling solution, squeeze the tip of the swab into the sampling solution several times, break the tail of the swab Rub the swab vigorously and discard the tail of the swab. Nasal and pharyngeal swabs can also be collected in the same virus sampling tube.
