This product uses an improved salt precipitation purification method to provide a safe and economical solution for High Weight genomic DNA extraction from blood samples, tissue samples, cultured cells, oral swabs, bacteria, and other samples. The extraction does not require the use of toxic phenol chloroform or any expensive reagents, making it the most economical reagent kit for nucleic acid extraction at present. This kit has no limit onthe amount of sample used and can flexibly adjust various amounts of samples. The obtained DNA can be directly used for experiments such as PCR, enzyme digestion, Southern hybridization, and the Third-generation sequencing.
Principles
SolPure DNA Kits is an improved salt precipitation purification method. (Blood samples are lysed in red blood cell lysis buffer to remove red blood cells, and white blood cells are collected by centrifugation.) After lysis, DNA is released into the lysis buffer. RNA is removed by RNASE A. High salt solution is added to precipitate proteins and impurities. Centrifuge to remove precipitate and obtain supernatant containing only DNA. Add isopropanol to precipitate and recover DNA. Wash with 70% ethanol to remove salt, and finally add Buffer TE to dissolve DNA.

| Proteinase K | 12 mg | 50 mg | 240 mg |
| Protease Dissolve Buffer | 1.8 ml | 10 ml | 20 ml |
| RNase A | 5 mg | 20 mg | 60 mg |
| Buffer TE | 10 ml | 60 ml | 250 ml |
RNase A and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 4 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Brucella abortus is an intracellular, blood-borne parasite. It is a Gram-negative coccobacillus that causes an infectious and contagious disease called Brucellosis. The disease primarily affects cattle but it can also be transmitted to humans from infected animals and consuming their products. The disease can lead to great economic loss especially in the dairy and agricultural industry. The Brucella abortus genome contains two DNA chromosomes in a circular confirmation; the first chromosome is approximately 2.1 Mb and the second chromosome is approximately 1.2Mb. Unusually it does not contain any plasmids or genomic islands that relate to pathogenicity and lacks many other genes that code for common virulence factors including capsules, fimbriae, exotoxins, cytolysins, resistance forms, or antigenic variation. The most common mode of transmission to humans is through the ingestion of unpasteurized milk and cheese products as the bacteria are present in the milk glands of infected female cows. In cattle transmission can also be through ingestion but in addition, the bacteria can persist in the reproductive tracts of males, namely seminal vesicles, ampullae, testicles, and epididymides, allowing sexual transmission. In humans the bacteria enter macrophages by phagocytosis and then live in compartments of vacuolar space along the endoplasmic reticulum. They persist by inhibiting host apoptosis and go onto form chronic disease causing lesions in the liver, spleen, bone marrow and kidneys. In cattle the bacteria additionally infect the trophoblast epithelial cells, which provide nutrition to the embryo. The trophoblast cells eventually lyse, releasing further bacteria into the blood stream of the embryo. The B. abortus cells in the blood stream go on to colonize the placenta and fetus in pregnant female cows, resulting in abortion of the fetus. Abortion can also result from insufficient anti-Brucella activity in the amniotic fluid. In humans, the disease can be either acute or chronic and some of the symptoms include fluctuating fever, chills, sweating, headache, muscle pain and weight loss. Once a person becomes infected they are prescribed a combination of tetracycline and streptomycin for 3-6 weeks. In cattle, additional symptoms include arthritic joints and retained after-birth.
