What Is the Workflow of Nucleic Acid Extraction Instrument and What Are the Precautions?

  Author:MeCan Medical–ultrasound machine manufacturers

The epidemic is still continuing, especially in winter, the temperature is low, and the virus is very suitable for survival. Therefore, in addition to taking personal protection measures, for some special industries or medical staff, regular nucleic acid testing is a method of effective prevention of virus prevention. one. So, we do nt know much about the equipment of the nucleic acid extraction instrument. Basic the device.

1. How is nucleic acid extracted

1. Crack cells and release nucleic acids. Use the liquid to destroy the sample cell structure, so that the DNA in the sample is free of the cracking system.

2. Separation and purification of nucleic acids. The protein combined with nucleic acids, as well as polysaccharides, lipids and other organisms and other unwanted nucleic acid molecules.

3. Concentration and precipitation of nucleic acids.

4. Purified nucleic acid. Purification is the process of completely separating other components in the DNA and cracking system, such as protein, salt and other impurities.

Second, the basic requirements and principles of nucleic acid extraction

1. To ensure the integrity of the first -level structure of nucleic acid, prepare for downstream experiments.

2. Eliminate the pollution of other nucleic acid molecules.

3. Organic solvents and high -concentration metal ions in nucleic acid samples have no inhibitory effect.

4. Pollution of other organisms in nucleic acid samples such as protein, polysaccharides, and lipid molecules to a very low level.

Third, precautions in the process of nucleic acid extraction

1. The air inlets and exhaust ports are located on the back of the instrument. At the same time, avoid dust or fibers from gathering at the air inlet to keep the air duct smooth.

2. Stay away from the charged circuit: The operator shall not dismantle the instrument without authorization, replace the component or the professional maintenance personnel who must have a certificate must be completed. Do not replace the element without connecting the power supply.

3. Instrument grounding: In order to avoid electrical shock accidents, the input power cord of the instrument must be grounded.

4. Nucleic acid extract instrument is at least 10cm from other vertical surfaces.

5. Avoid placing the instrument near the heat source, such as electric heaters; at the same time, in order to prevent the short circuit of electronic components, water or other liquids should be avoided.

6. Installation environment of the instrument: normal atmospheric pressure, temperature 20-35 C, typical use of temperature 25 C, relative humidity 10%-80%, smooth air flowing into 35 C or below.

The above briefly introduces the basic knowledge of nucleic acid extract instruments. I believe that everyone has a certain understanding of this device. In fact, as one of the commonly used inspection equipment, its clinical application is becoming more and more extensive, and its advantages have become more and more advantages. Highlight. As a manufacturer of nucleic acid extraction instrument equipment, Proud Medical Equipment currently has a lot of nucleic acid extraction instruments, good performance, and good after-sales service.

What Are the Issues to Pay Attention to Before the Sampling of Biochemical Chemistry?
  Author:MeCan Medical–ultrasound machine manufacturersThe fully automated biochemical analyzer is used for conventional health inspection and disease screening experiments. Through a full set of biochemical inspections, it understands its own health status. Due to its fast measurement speed, small reagent consumption and high accuracy, it has been widely used in units at all levels. In the biochemical inspection, in order to ensure the accuracy of the test results, what problems should we pay attention to before sampling?Avoid tension and emotional excitement: Otherwise, it can affect God's endocrine function, affect breathing, and increase lactic acid.Avoid strenuous exercise: Generally, it is advisable to do not do severe exercise within 24 hours before blood drawing. Blood is collected in the early morning. Inpatient patients can take blood before getting up. Patients who rushed to the outpatient clinic should take at least 15 minutes and take blood to take blood. Strong muscle exercise significantly affects the metabolism in the body, causing changes in certain component concentrations in the blood, such as lactic acid, creatine kinase (CK), citizen amin aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphate, alkaline phosphate Enzyme (ALP), glucose (GLU), etc.Avoid drinking before blood: drinking before taking blood can increase blood lactic acid, uric acid, etc. quickly, and continuous drinking can see AST, Alanine transaminase (ALT), -glutamyl metastases (-GT), and -GT rise up obvious. Those with long-term alcohol often have triglycerides, and -GT will also be abnormal for a long time.Pay attention to a reasonable diet: In addition to emergency or other special reasons, it is generally advocated that after 12 hours of fasting for 12 hours, blood takes blood on an empty stomach, extending the empty time (hunger) or the chemical composition of blood after meals will cause changes. For example, blood sugar and protein are reduced, and bilirubin increases; postprandial blood glucose, potassium, alkaline phosphatase and triglyceride are usually increased, inorganic phosphorus decreases, and serum can be turbid. In addition, the amount of diet and quality also affects the test results. For example, a high -protein diet can increase serum urea, blood ammonia, uric acid; high -fat diet cause chlorophytic sepsis and cause serum turbid Or concentrated; beverages containing caffeine can release catecholamine. The blood components are affected by the diet. The ingredients with large variables include potassium ions (K), GLU, total cholesterol (TC), triglyceride (TG), inorganic phosphorus (IP), etc.Avoid the impact of drugs: Many drugs (hormones, hypoglycemic drugs, diuretic drugs, antiepileptic drugs, anticancer drugs, etc.) can increase or decrease some test items after entering the human body. Pay attention to the history of medication when analyzing and judging the results.The impact of the position when taking blood: change (standing, sitting, and lying position) changes can cause significant changes in certain testing indicators. Therefore, it is recommended to take blood for 5 minutes when taking blood.
