The new 9 positive cases of this round of the epidemic strains mainly belong to Omicron BA.5 rampant, around the new crown epidemic one after another, the country has resumed a state of intense prevention and control, Nanjing, Wuhan, Zhangjiajie and other places to carry out large-scale nucleic acid testing work.
In this tense environment, how to avoid "false negatives" is the top priority of epidemic prevention and control. Therefore, the choice of virus sampling tube is the edge to ensure the accuracy of nucleic acid testing. However, many companies are fast in the production of "quantity", but shallow in the research of "quality", resulting in a wide range of virus sampling tubes on the market. As a company specializing in the field of virus sample processing for many years, Hualikang Biomedical understands the characteristics of a "right" virus sampling tube.
The accuracy of nucleic acid test results is closely related to the composition of the sampling solution.
Improperly formulated products may inhibit enzyme activity in the PCR system, resulting in "false negative" test results and inorganic salt precipitation during transport.
Advantages of virus sampling tubes.
①. The wall and cap of the sampling tube are thickened to resist static extrusion and dynamic impact. Conical design at the bottom, resistant to centrifugation and shock. Leak-proof ring on the inside of the cap and impermeable design on the bottom of the cap, double insurance to eliminate leakage. Ensures no leakage of sample during transportation. Complies with UN2814SHENGWU safety regulations.
②, the tube body and cap are made of polypropylene, no deformation at high temperature and high pressure (121℃, 15min) and no brittleness at low temperature (-80℃). Preservation process without leakage, to ensure that the sample does not leak during the preservation process. Meet the United Nations biosafety regulations.
③, tube body and tube cover without pyrogen, no DNA, RNA enzymes, toxic residue test in line with the standard, no toxicity to the sample. Ensure that the sampling tube itself will not have toxic effect on the sample.
④, fully compatible or semi-automatic microbiological testing workstation, the product can stand (conical bottom leak-proof design, with skirt can stand,) suitable specifications, easy to use and save.
⑤, unique flared design, so that the sampling tube can be automatically inserted into the lid with the rotation of the lid.
Advantages of virus preservation solution.
①、Our virus preserving solution is produced in fully automatic quantitative dispensing equipment in a class 100,000 operation space in a class 100,000 purification workshop, which ensures the sterility of the whole production process. The final gamma irradiated product avoids contamination of the preservation solution by other bacteria due to the production process control.
②, we are through a large number of experiments, from the base solution, buffer system, protein stabilizer, cryoprotectant, amino acids and other nutrients on the cells to summarize and summarize the most suitable for cell production and preservation of the preservation solution formula, to ensure the efficient preservation of the virus, and greatly improve the positive rate of virus culture.
③, antibiotics, the choice of gentamicin and fungal antibiotics, better inhibition of bacteria and fungi. Avoid possible human sensitization caused by penicillin in traditional sampling solution.
The advantages of sampling swab.
①, the head of the sampling swab is nylon flocked material (also rayon and polyester material), persistent cadre the use of medical plastic material ABS. national influenza surveillance program recommended material
②, non-cotton material, does not contain saturated fatty acids and other substances, will not affect the results of PCR experiments, swab rod, non-wood or bamboo
③, does not contain formaldehyde and other substances, no toxic effect on cells, viruses, will not affect the positive rate of the experiment. The swab as a whole, gamma sterilization, non-ethylene oxide sterilization, no toxic effect on cells, viruses, will not affect the positive rate of the experiment.
At present, the epidemic prevention and control situation is not optimistic, multiple, epidemic situation after another, all regions are always tense prevention and control screening this string. The actual virus sampling process, various uncertainties occur from time to time, affecting the accuracy of nucleic acid detection, especially the cunning delta virus is highly infectious and highly hidden, the requirements for detection need to be improved, the choice of a stable and useful virus sampling tube is essential.
As a company specializing in the field of virus sample processing for many years, our professional and unique "craftsmanship" virus sampling products will be your trustworthy choice!
Hualikang Biomedical is standing together with the people of China to fight the epidemic and overcome the difficulties together! We will succeed in the end!
