Lnjnbio Magnetic Beads for Blood Genomic DNA Extraction Kit (마그네틱 비드 방식)231010

【제품소개】

이 제품 is designed for the extraction, 농축, and purification of genomic nucleic acids from fresh, 언, or blood samples containing anticoagulants. Under the influence of guanidine salts, cellular lysis occurs, releasing the nucleic acids. Through specific adsorption by magnetic beads, the nucleic acids are separated from other contaminants in the sample. They are then washed with a buffer solution to eliminate proteins and residual guanidine salts. 궁극적으로, purified nucleic acids are retrieved via elution and magnetic adsorption. The resulting product is suitable for applications such as PCR amplification, nucleic acid detection assays, gene mutation analysis, and sequencing experiments.

【제품의 장점】

1. It enables efficient lysis and binding in one step even for challenging samples like whole blood, eliminating the need for intermediate pauses to add additional reagents.

2. The extraction process does not require the addition of Proteinase K, allowing for ambient transportation and storage conditions.

3. The extracted genomic DNA exhibits high purity, yields, and intact electrophoresis bands.

4. It boasts high extraction efficiency, completing the entire process in approximately 20 분, ideally suited for the extraction of 200-400 μL whole blood samples.

5. It offers strong versatility, being compatible with automated nucleic acid extraction systems from various manufacturers.
