pengenalan

SiO₂ beads are magnetic microspheres with a layer of silicon dioxide (SiO₂) on the surface, thus exposing a large number of silicone hydroxyl groups (-Si-OH) on the surface.

Ciri-ciri

High specificity and purity: this is its greatest advantage. In the presence of leaving liquid salts, the specificity of adsorption of nucleic acids by silica hydroxyl groups is much higher than the adsorption of impurities such as proteins and sugars. Combined with effective cleaning (ethanol is commonly used), extremely pure nucleic acids can be obtained, which is ideal for downstream sensitive applications (cth. PCR, penjujukan).

Efficient and reliable: high efficiency and quality recovery for nucleic acid extraction from all types of samples (darah, tisu, sel, tumbuhan, bakteria, dll.).

Automation-friendly: the whole process (binding-washing-elution) is simple and straightforward, making it extremely easy to automate high-throughput operations.

Biocompatible: Silica surfaces are hydrophilic, which is “gentler” than hydrophobic surfaces and helps to reduce non-specific adsorption of certain biomolecules.

Permohonan

Genomic DNA extraction: High-quality genomic DNA is extracted from a variety of biological samples.

Viral RNA/DNA extraction: cth. HPV, HIV, HCV viruses as well as the new coronavirus (SARS-CoV-2) nucleic acid detection, the majority of extraction kits are based on this principle.

Pengekstrakan DNA plasmid、Total RNA extraction、Trace amounts of DNA are extracted from ancient samples such as fossils and trace and highly degraded samples (cth., darah, rambut)

Soalan Lazim

Q: How to avoid nucleic acid degradation when using Silicon-based Magnetic Beads for nucleic acid extraction?
A: Semasa proses pengekstrakan asid nukleik, Kit dan bahan habis pakai bebas RNase harus digunakan dan dikendalikan pada suhu rendah untuk mengurangkan aktiviti nuklease dan mencegah degradasi asid nukleik.

Q: Can Silicon-based Magnetic Beads be reused?
A: Ini bergantung kepada reka bentuk dan penggunaan manik magnet. Sesetengah manik magnet boleh digunakan semula selepas pembersihan dan penjanaan semula yang betul, tetapi penggunaan berulang boleh menyebabkan prestasi manik merosot.

Q: How to choose suitable Silicon-based Magnetic Beads?
A: Ciri-ciri molekul sasaran, keadaan eksperimen, dan jangkaan kecekapan penulenan perlu dipertimbangkan apabila memilih manik magnetik. Adalah disyorkan untuk berunding dengan pembekal profesional untuk memilih jenis manik magnet terbaik berdasarkan aplikasi khusus.
