本产品专门用于冠状病毒、流感病毒、手足口病毒、麻疹风疹病毒等各种病毒及相关样本的采集和运送,方便样品的运输和异地检测。
本产品具有以下特点:
1. 保存液构建的中性环境有利于增加病毒的生存时间,不破坏病毒外壳,方便长途运输。
2. 适用于各种拭子的采集保存和运输,包括口腔拭子、咽喉拭子、鼻腔拭子、阴道拭子等。
3. 保存的样品可以直接用于后续的核酸纯化及检测。
4. 本产品只能用于科研。
使用方法
注意:本产品为非灭活型病毒保存液,不含病毒灭活剂,因此操作人员必须按处理传染性样品的方法进行相应的防护,必须在合乎国家规定的实验室进行所有操作。
1. 先将本产品稀释 10 倍,得到 1×保存液。如若需要 10L 的非灭活型病毒保存液,取 1L 本产品,加入 9L 超纯水充分搅拌混匀即可。
2. 稀释好的 1×保存液进行分装。
3. 采样前,在含有非灭活型病毒保存液的采样管的标签上标注相关样品信息。
4. 根据不同的采样要求,用采样拭子在相应的部位和器官采样。具体采样方法如下:
a) 鼻拭子:将拭子头轻轻插入鼻道内鼻腭处,停留片刻后缓慢转动退出。
b) 咽拭子:用拭子擦拭双侧咽扁桃体及咽后壁后退出。
c) 尿道采样:对男性,用拭子插入尿道约 2cm 处旋转,静止数秒后退出。对女性,抹去宫颈口粘液,用拭子插入宫颈管 1-2cm 处后退出。
d) 其他拭子采样:本手册暂不详述。
5. 迅速将拭子放入含有非灭活型病毒保存液的采样管中,将拭子在样品管中旋转 15 秒。
6. 将采样拭子在折断处折断,丢弃把柄端,旋紧管盖。
7. 新鲜采集的标本应在4°C-25°C下24小时内运送至实验室,未能24小时内送至实验室的,应置于-20°C或以下保存。
This product is specially used for the collection and transportation of samples containing coronavirus, influenza virus, hand‑foot‑and‑mouth virus, measles‑rubella virus and other viruses, facilitating sample delivery and off‑site testing.
Product Features
1. The neutral environment created by the preservation solution helps prolong virus survival time without damaging the viral envelope, making it suitable for long‑distance transportation.
2. Suitable for sample collection, preservation and transportation using various swabs, including oral swabs, throat swabs, nasal swabs, vaginal swabs, etc.
3. Preserved samples can be directly used for subsequent nucleic acid purification and detection.
4. This product is for research‑only use.
Instructions for Use
Note: This is a non‑inactivating virus preservation solution and contains no virus‑inactivating agents. Operators must wear appropriate protective equipment for handling infectious samples, and all operations must be carried out in laboratories that meet national regulatory requirements.
1. Dilute this product 10‑fold to prepare 1× preservation solution. For example, to prepare 10 L of non‑inactivating virus preservation solution, take 1 L of this product, add 9 L of ultrapure water and stir thoroughly until well‑mixed.
2. Aliquot the prepared 1× preservation solution.
3. Before sampling, mark relevant sample information on the label of the sampling tube pre‑filled with non‑inactivating virus preservation solution.
4. Collect samples from corresponding sites using sampling swabs according to sampling requirements. Specific sampling procedures are as follows:
a) Nasal swab: Gently insert the swab tip into the nasopalatine area of the nasal passage, pause briefly, rotate slowly and withdraw the swab.
b) Throat swab: Swab both palatine tonsils and the posterior pharyngeal wall with the swab, then withdraw.
c) Urethral sampling: For males, insert the swab approximately 2 cm into the urethra, rotate, hold for several seconds and withdraw. For females, wipe away mucus at the cervical orifice, insert the swab 1‑2 cm into the cervical canal and withdraw.
d) Other swab‑based sampling methods: Not detailed in this manual.
5. Immediately place the swab into the sampling tube containing non‑inactivating virus preservation solution, and rotate the swab inside the tube for 15 seconds.
6. Break the swab at the pre‑scored break‑point, discard the handle portion, and tighten the tube cap securely.
7. Freshly collected specimens must be transported to the laboratory within 24 hours at 4°C–25°C. Samples that cannot be delivered to the laboratory within 24 hours should be stored at -20°C or below.
