المهنية في صناعة الخرز المغناطيسي الحيوي
تكنولوجيا استخلاص الحمض النووي الثورية: شنغهاي لينغجون بيو 220011 الخرز المغناطيسي يقود حقبة جديدة من كفاءة البحث العلمي
غالبًا ما يبدأ تقدم البحث العلمي بابتكارات صغيرة في الأدوات التجريبية. في عدد لا يحصى من المختبرات, تحدث ثورة تكنولوجية صامتة.
في مجالات علم الجينوم, التشخيص الجزيئي, and biomedical research, nucleic acid extraction and purification are fundamental steps in almost every experiment. Traditional methods are time-consuming and labor-intensive, with low recovery rates and difficult to guarantee purity, especially when dealing with trace or trace samples.
ال 220011 fragment sorting magnetic beads launched by Shanghai Lingjun Biotechnology Co., المحدودة. are changing this status quo, becoming a new choice for scientific researchers at home and abroad with its excellent performance and reliability.
Technological innovation
220011 magnetic beads are made of superparamagnetic silica matrix with Si-OH active groups, with an average particle size of 500 نانومتر, excellent suspension (شكل 1), and a semi-sedimentation time of more than 1 hour.
The magnetic saturation strength of this magnetic bead reaches 65±5 emu/g, which has strong magnetic responsiveness and can complete the separation operation in a short time, greatly improving the experimental efficiency.
Superior performance
The most striking feature of 220011 magnetic beads is their recovery rate of over 95%, which can maintain this high level of recovery even when treating trace DNA samples up to 20 ng/μL.
This means unprecedented recovery efficiency and reliability of experimental results for those experiments where samples are precious and rare. Whether it’s clinical or archaeological samples, researchers can now conduct experiments with greater confidence.
The magnetic beads offer excellent suspension properties and adsorption capabilities, allowing them to be evenly dispersed in solution, maximizing contact with nucleic acid molecules.
Widely used
220011 fragment sorting magnetic beads are suitable for nucleic acid extraction of a variety of sample types, including but not limited to: the extraction and purification of genomic DNA from whole blood, animal tissues, الأنسجة النباتية, bacteria, plasmids, إلخ., as well as the separation and purification of viral DNA/RNA and small fragment DNA/RNA.
In particular, it excels in the extraction of serum/plasma cell-free DNA/RNA fragments, meeting the current urgent needs in the field of liquid biopsy and non-invasive diagnostics.
Experimental case: 100bp exogenous nucleic acid fragments were added to the serum, and the simulation experiment was carried out, and the sample was extracted and then qPCR was performed.
Result analysis：It shows that the reagent system extracts nucleic acids with good purity and reproducibility.
The electrophoresis results were as follows, sample starting volume: 200 μL, 80 μL elution, 6 μL top sample electrophoresis, agarose gel concentration of 1%, 120 V, electrophoresis for 30 min.
Result analysis：As can be seen from the above figure, the experimental results are reproducible and can meet the experimental requirements of downstream qPCR, ddPCR and high-throughput sequencing.
Easy to operate
Compared with traditional methods, the operation process of 220011 magnetic beads is simpler and does not require the use of toxic reagents such as phenol/chloroform, greatly reducing the health risks of experimenters.
This product is suitable for automated workstations and automatic nucleic acid extraction instruments, realizing one-click automatic extraction, reducing human operation errors and improving the repeatability and consistency of experimental results.
