What does the saliva collector do to collect saliva?

What does the saliva collector do to collect saliva?

Saliva, commonly known as saliva, is a colorless and thin liquid excreted by the oral cavity and internal glands, with a pH of 6.6 to 7.1. An adult can excrete 1000 to 1500 ml of saliva throughout the day and night.

The composition and function of human saliva: 99% of human saliva is water, follow by substances such as amylase, peroxidase, mucin, phospholipids, phosphoprotein amino acids, potassium, calcium, and magnesium. These substances have the functions of digesting food, antibacterial, and protecting gastric mucosa.

Disadvantages of saliva: Saliva can also spread diseases through the human body with germs.

What can the saliva sampled by the saliva collector be used for?

1. Check for AIDS: In fact, you can find out whether your body is infected with HIV through saliva. The method is quick and easy.

2. Predicting ovulation: Regardless of whether a woman is breastfeeding or not, the glucose content in her saliva is sharply add 5 days before ovulation and 6 days before ovulation. So this can predict the ovulation period, which is helpful for contraception or fertility.

3. Disease prevention and cancer prevention: The mucus protein in saliva can neutralize part of the gastric acid, cause precipitation, attach to the gastric mucosa, form a protective layer, prevent peptic ulcers, and not only kill or inhibit staphylococcus, typhoid bacillus, Escherichia coli, hemolytic streptococcus, etc., and also greatly reduce the toxicity of carcinogens such as aflatoxin, benzopyrene and nitrosamines, and even become harmless substances.

4. Healing wounds: Saliva is rich in nerve growth factors and epidermal growth factors,

which make them accumulate in large amounts at the injured area and repair the wound together with the proliferated capillaries. In addition, the continuous production of collagen fibers can promote hemostasis and wound healing.

The benefits of using saliva samples: Compared with blood samples, saliva samples are easier, more convenient, safer, painless, and non-invasive. The method of collecting saliva samples reduces the risk of contamination and adds the convenience of sampling and inspection. The subjects sampled by themselves. The saliva sample collected by the saliva collector can be use in the saliva preservation fluid to replace blood DNA and is widely use in epidemiological research,

characteristic medicine, drug response monitoring, genetic disease diagnosis, disease probability prediction, and healthy life counseling.

What is the difference between a nasal swab and a throat swab

What is the difference between a nasal swab and a throat swab

The accuracy of detecting nasal swabs and throat swabs is usually the same. The main difference lies in the sampling method and sampling site. For nasal swabs, the nasal swab is mainly use to dip the secretions on the surface of the nasal mucosa inside the nasal cavity for detection. In fact, pharyngeal swabs are collect from the oropharynx for testing to determine whether the sampler is infect with the new coronavirus.

Under standardized operations, throat swabs and nasal swabs are two methods for collecting specimens. There is no difference in essence. Both are for collecting specimens from the pharynx. The difference is that one enters from the oral cavity, and the other is from the mouth. Enter the nasal cavity.

For throat swabs, the sampler can see the sample site, but it may cause nausea, vomiting, and other reactions, and because the pharyngeal virus content is affect by diet, drinking, and swallowing actions, it will affect it to a certain extent Throat swab detection rate.

When collecting nasal swab specimens, the swab will enter the nasal cavity. If the operation is standardize, it will cause less irritation to the mucous membrane. However, because the pharynx sampling position cannot be seen, the main reliance is on the sensory resistance of the hand. For those who require more technology, the tools use are more complex. If the operation is improper, it will cause some irritation to the nasal mucosa. Therefore, it is not recommended to do nasal swabs for patients with sinusitis and allergic rhinitis to avoid damage to the nasal cavity.

Advantages of cell preservation solution

Advantages of cell preservation solution

Currently, most of the protective agents for cryopreservation of cells are glycerol or dimethyl sulfoxide. In fact, these two substances can increase the permeability of cell membranes to water. In addition, slow freezing can make the water in the cell seep out of the cell and reduce the ice crystals in the cell. The formation of ice crystals reduces cell damage caused by the formation of ice crystals.

Cells should be resuscitate by a fast melting method, which can ensure that the extracellular crystals melt in a short time,

and avoid damage to the cells due to the infiltration of water into the cells to form intracellular recrystallization; non-program cooling, -80℃ Cryopreservation in a low-temperature refrigerator for up to 3 years can ensure the safety of cryopreserved cells; cryopreservable plates (cell culture plates) can be use for cryopreservation of hybridoma cells. The cell preservation solution has a diluting effect and can be separated.

A large number of effective cells embed in the mucus allows more cells of test value to be preserve, providing a sufficient number of cells to ensure the accuracy of the test results;

at the same time, the process samples can be completely remove after low-speed centrifugal filtration The mucus in the sample effectively prevents the mucus from interfering with the test results of the sample.

The cell preservation solution can be make into a uniform monolayer cell sheet after low-speed centrifugation,

which meets the inspection requirements.

summary

Cell preservation solution is a general-purpose cell cryopreservation solution that can be use to freeze cell lines of humans and various animals; cell cryopreservation is an important technical means for cell culture, introduction, preservation and ensuring the smooth progress of experiments. In cell line establishment and line establishment, it is very important to freeze the original cells in time. In the preparation process of hybridoma monoclonal antibodies,

the cryopreservation of hybridoma cells and subcloned cells obtained from each cloning is often an indispensable experimental operation.

Because when a stable cell line or a cell line that secretes antibodies is not established,

the cell culture process may cause the experiment to fail due to cell contamination,

loss of antibody secretion ability or genetic variation, etc ,

if there is no original cell Frozen storage will be abandoned because of the above-mentioned accidents.

How is a throat swab used

How is a throat swab used

A throat swab is a throat swab that is used to check for lesions and take a throat sampling. It can be said to be a detection method to understand the patient’s condition, oral mucosa, and pharynx infection. Because the pharynx is affected by infections caused by external bacteria when the body’s body or local resistance is reduced, the doctor needs to collect some cells or viruses for observation when we seek medical treatment, so as to understand the patient’s disease. Illness.

The advantages of throat swabs:

1. A release rate of more than 90% for the collected samples;

2. In fact, one hand operation, no pollution, easy to use;

3. Automobile innovation, independent packaging;

4. Unique craftsmanship increases the comfort of the collected person;

5. Under normal temperature conditions, the samples can be stored for 12 months;

6. Pharyngeal Swab The swab set is a combination of swab and preservation solution, which can be used to collect samples once per person.

In fact, throat swabs are divided into oropharyngeal swabs and nasopharyngeal swabs. Nasopharyngeal swabs are also called nasal swabs and nasal swabs, but oropharyngeal swabs and oral swabs are not the same.

Throat sampling method

1. First, check personal information with the subject.

2. Then tear off the outer packaging of the sample and take out the sample;

3. Let the examinee open his mouth to make an ah sound to expose the mouthpiece, and if necessary, use a tongue depressor to press down the tongue (lightly press the front 2/3 of the tongue and the back 1/3);

4. Take out the swab, gently and quickly wipe the bilateral pharyngeal tonsils and pharyngeal wall 3 times, and put the swab head into the preservation solution.

5. The bottle mouth is firmly buckled and folded and stored at a later stage, the rear end will be removed, and the tight tube will be tightened (cap off the test cap),

6. Finally, check the user’s name again;

7. And put it in a sealed bag, and put it in the transfer box, and then quickly check the sample in the laboratory.

nylon flocked swab

nylon flocked swab

Our flocked swabs feature perpendicular nylon fibers that optimize specimen collection and elution into transport media. The swabs also feature a molded breakpoint that allows you to safely and easily break off the swabstick, and several breakpoint options are available for different tubes.

In fact, our nylon flocking cotton swabs are produce in a 100,000-level GMP production workshop. Our factory has ISO13485 certification, GMP certification, CE and FDA for swabs. In fact, we produce many types of flocking cotton swabs. Our goal is to keep improving, quality first, rapid response and continuous improvement.

Why use flocking swabs?

The flocking swab is made of nylon fiber flocking technology, and the front end is coated with nylon short fiber fixed in a vertical way, so that there is no absorption hole in the sampling area of the whole sampling swab, and the sampling sample will not be dispersed in the fiber, which is conducive to faster and more efficient elution. Traditional swabs can not collect and elute samples completely, while flocking swabs can elute 95% of the samples. Therefore, the use of flocked swabs has great advantages for various sample collection applications.

What is a flocked swab?

Flocking swab is to deposit nylon fibers on the surface of medical ABS rod in a certain direction by electrostatic field in order to form brush layer. The layers are fully parallel and perpendicular to the surface of the inner rod. The brush head can be used for DNA collection, which can be used for sampling of oral cavity, nasopharynx and other natural cavities of human body, and can also be used for laboratory testing.
