Introduction

Blood samples contain rich DNA, including mitochondrial DNA, genomic DNA, circulating DNA (mostly released into blood after tumor cell apoptosis) in white blood cells, as well as parasitic viral or microbial DNA. These DNA are important parameters in clinical testing or diagnosis, which are also valuable materials for medical research. There are three main issues with extracting DNA from blood samples:

1. The sample is highly infectious, posing great harm to operators and the environment.

2. The source of DNA is complex and aportion of the nucleic acid, such as viral DNA or free DNA, may be lost during the operation, leading to downstream detection failure;

3. Blood sample contains a large amount of impurities and inhibitory factors.

Currently there are many methods available for extracting DNA from whole blood samples, such as phenol chloroform extraction, salting out method, etc. However, these methods require pre-treatment of blood sample, which removes red blood cells and isolate white blood cells in the first step. Due to the requirement that it cannot inactivate or kill pathogens during the process of removing red blood cells, the waste liquid (red blood cell lysate) and consumables may be contaminated by pathogens and become infectious, posing a danger to the entire laboratory environment and operators. In addition, during the process of removing red blood cells, useful nucleic acid information such as viruses, microorganisms, or circulating DNA is also lost, leading to experiment or detection failures.

The HiPure Blood DNA Kits series provided by Magen Company uses silica gel column purification technology, which can directly lyse whole blood samples without the need for white blood cell separation. Whole blood samples are directly mixed with lysates and proteases, resulting in the inactivation of pathogens, greatly reducing the infectivity, environmental pollution, and the chance of operators being infected. Due to the direct lysis and digestion of samples, except lymphocyte DNA, other circulating DNA as well as DNA from viruses and microorganisms, can also be recovered.

This product provides fast and easy methods for purification of total DNA for reliable PCR and Southern blotting. Total DNA (e.g., genomic, viral, mitochondrial) can be purified from whole blood, tissue and culture cells.

Principle

This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High quality DNA – meet a variety of downstream applications, including PCR, qPCR, enzyme digestion, hybridization, etc.
• Fast – without separation of leukocytes, organic extraction or ethanol precipitation
• Simple – all nucleic acids can be obtained by direct digestion
• Pertinence – specially designed for isolating DNA from 3-10ml blood and related body fluids
• Wide applicability – handle a variety of liquid samples
• Economy – excellent cost effectiveness performance

Storage and Stability

Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

Purchase Guide

*Note：Leukocyte protocol can be used when large volume whole blood samples need to be processed. Whole blood was treated with red blood cell lysate, and white blood cells were obtained by centrifugation before extraction

Blood samples contain rich DNA, including mitochondrial DNA, genomic DNA, circulating DNA (mostly released into blood after tumor cell apoptosis) in white blood cells, as well as parasitic viral or microbial DNA. These DNA are important parameters in clinical testing or diagnosis, which are also valuable materials for medical research. There are three main issues with extracting DNA from blood samples:

Character

High flatness sample shelf:

Silicone oil thermal conductive shelf, high-precision processing method of upper and lower clamping, shelf temperature uniformity can reach ±0.5°c

Integrated cavity:

Integrated chamber, the shelf and cold trap are located in the same chamber, the steam conduction is faster and the freeze-drying effect is better

Refrigerating and heating control system:

Using thermally conductive silicone oil with a high temperature range and precise PID control algorithm, the control accuracy can reach ±0.5°C. Sample shelf temperature range: -70°C~ +80°C

Freeze-drying endpoint testing system:

The pressure comparison method is used to determine the freeze-drying end point. The freeze-drying end point test can be automatically performed after the analytical drying stage to ensure that the moisture content of the material reaches the standard requirements.

Vacuum precise control and adjustment system:

The sublimation and analytical drying processes are controlled and adjusted with high precision to make the freeze-drying process warmer and the sample sublimation more reliable.

Pulse backfill system:

Three backfilling modes can be selected: slow, medium and fast, which avoids the problem of effective substances being blown away and lost due to the aeration of granular and flocculent materials after freeze-drying.

Manual automatic mode selection:

Manual mode is used to explore process parameters (strong human intervention), automatic mode is used in the mature stage of the process, one-click operation, simple and convenient

Data recording and analysis system:

Through the PC host computer, all operating parameters and background parameters of the equipment can be recorded in real time, and all parameter action changes and action changes of operating components can be recorded. 

Freeze-drying process recipe storage function:

The host can store 60 sets of fixed or user-defined freeze-drying process recipes, and the PC can store >10,000 programs (depending on the computer hard drive)

Eutectic point test function:

The eutectic point temperature of the product can be tested offline and online, and the spectrum can be analyzed manually or automatically (optional)

Remote control system:

The operating status of the device can be monitored remotely, and the device can be monitored in real time via WiFi or the cloud.

Mobile phone monitoring system:

You can monitor the operating status of the equipment with your mobile phone, which is simple and convenient (optional)

Cold trap defrost system:

The hot air defrosting method has high safety performance; the defrosting speed is fast, which solves the inconvenience caused by traditional immersion defrosting.
