What is the difference between inactivated and non-inactivated virus preservation solutions

Label: virus preservation solution, inactivated, non-inactivated

Virus preservation solution, also known as swab preservation solution, is a commonly used method for extracting virus samples. Combined with PCR, it can be used for rapid detection of viral diseases. However, not every sample collection site has PCR detection capabilities. Sometimes it is necessary to find a suitable storage container for the collected virus swabs, and then transport them to a laboratory or hospital capable of testing. Hubei New Desheng Material Technology Co., Ltd. specially developed two virus preservation solutions for this need, which are specially used for the preservation of swabs in virus sampling tubes. The two virus preservation solutions are: inactivated and non-inactivated virus preservation solutions. Each has the following characteristics:

1.Virus storage solution (inactivated type) 2.Virus storage solution (non-inactivated type)

Appearance 1. Colorless transparent liquid 2. Red transparent liquid

Applicable types of viruses 1. Novel coronavirus, various influenza, avian influenza, hand-foot-mouth urticaria and other viruses, conventional RNA extraction

2. Novel coronavirus, various influenza, avian influenza, hand-foot-mouth urticaria and other viruses, conventional RNA extraction

PH value 7.5-8.0 7.5-8.0

Transportation temperature (within 48 hours after sampling) 0-35℃ 4-25℃

Storage temperature (more than 48 hours after sampling) 0-35℃ -70℃

Storage time: 30 days a year

Applicable kit method 1. Fluorescence PCR method, combined probe anchoring polymerization sequencing method, constant temperature amplification chip method, magnetic particle chemiluminescence method, colloidal gold method

2. Used in laboratory or hospital research

Can it be sterilized? 1. It can be sterilized by EO or by irradiation

2. It can be sterilized by EO or by irradiation

Dosage per tube 1. Take a pharyngeal (nasal) swab as a standard, and it is generally recommended to add about 3ml to a 10ml tube

2. Take a pharyngeal (nasal) swab as a standard, a 10ml tube generally recommends adding about 3ml

Laboratory (hospital) qualification None Level 2 and above

It can be seen from the above table that, compared with the inactivated virus storage solution, the non-inactivated virus storage solution requires more stringent storage and processing conditions, and should be sent to the testing laboratory for processing as soon as possible within 48 hours after sampling. The new coronavirus is currently managed temporarily according to the second category of pathogenic microorganisms in the classification of pathogenic microorganisms. According to the latest version of the new coronavirus laboratory biosafety guidelines, if the original sample cannot be reliably inactivated, the nucleic acid test should be carried out in the biosafety headset laboratory, and the personal safety of the third-level biosafety laboratory should be used. Protection (it is recommended to wear at least work clothes, disposable work caps, double gloves, medical disposable protective clothing, medical protective mask activities. Li Songfeng filter ventilator, protective face screen or goggles, work shoes or rubber boots, waterproof boot covers). Every virus sampling tube manufacturer can choose according to actual market conditions!
