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 tissue, whole blood, plasma, serum, buffy coat, bone marrow, other body fluids, lymphocytes, cultured cells.

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).

These kits provide everything required to isolate and purify inclusion body proteins from induced bacterial cultures. First a proprietary Cell Lysis Reagent is used to selectively lyse the cells and release inclusion bodies in their solid form. Next, inclusion bodies are dissolved and their contents released using the provided IB Solubilization Reagent. Inclusion body proteins are then further purified using spin columns for rapid and convenient buffer exchange and desalting. This kit provides a convenient way to screen recombinants prior to scaling up.
ProteoSpin™ Inclusion Body Protein Isolation Micro Kit
The process is efficient and streamlined and can process up to 12 samples in only 60 minutes. Each spin column is able to recover up to 50 µg of acidic or basic proteins. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.
ProteoSpin™ Inclusion Body Protein Isolation Maxi Kit
The procedure is efficient and streamlined and can process up to 4 samples in approximately 2 hours. Each spin column is able to recover up to 12 mg of acidic or basic proteins from 100 mL of induced bacterial culture. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.
About Inclusion Bodies
Bacteria are widely used for the expression of different proteins. However, 70-80% of the proteins expressed in bacteria by recombinant techniques are typically contained in insoluble inclusion bodies (i.e., protein aggregates). The protein of interest found in these subcellular structures is often inactive, due to incorrect folding. The production rate of recombinant proteins stored in inclusion bodies is invariably higher than those synthesized as soluble proteins. The reason behind this is thought to be the resistance of insoluble proteins to proteolysis by cellular enzymes. In addition, separation of insoluble recombinant proteins in inclusion bodies is considerably easier than that of soluble proteins. These factors have been the major influences favoring scale-up of high-value proteins using bacterial fermentation for example. Procedures for the purification of the expressed proteins from inclusion bodies are often labour-intensive, time-consuming and not cost-effective. This kit provides the essential reagents for cell disruption, inclusion body solubilization and purification using spin column chromatography – all optimized to work together thereby simplifying the process and saving a tremendous amount of time and cost.
