Avantages du produit:

 Superior suspension performance with high adsorption rate for small DNA fragments and a half-settling time exceeding 1 hour.

Featuring ultra-strong paramagnetic response and nano-scale magnetic core design, achieving rapid magnetic activation and uniform dispersion within 30 seconds—eliminating cumbersome steps in traditional centrifugation methods.

Exceptional stability with acid/alkali resistance and interference tolerance, ensuring strict batch consistency for high-throughput automated platforms, significantly boosting experimental efficiency. Flexible adaptability compatible with diverse sample types (sérum, cellules, tissus) and downstream applications (NGS, qPCR, magnetic bead ELISA), enabling multi-purpose use to reduce costs.

 Broad Application Scenarios Empowering Multi-Field Research Molecular Biology:

 Particularly suitable for small fragment and trace DNA extraction/purification, with high adsorption capacity for purifying 100 bp-50 kb DNA fragments for sequencing, restriction enzyme digestion, labeling, ligature, and cloning.

Diagnostic de la maladie: Tumor marker isolation, détection d'agents pathogènes.

Drug Development: Antibody purification, targeted vector construction.

Food Safety & Environmental Monitoring: Rapid microbial enrichment.

Experimental cases:

Using Magnetic Beads 220012 for DNA fragment purification (bilateral length sorting method), 100μl sample (containing 1μg total non-dye DNA Marker, sizes 100-5,000 bp). First round: Add 2X-0.45X volume of sorting magnetic beads for DNA fragment purification. Second round: Add 0.2-0.15X volume of sorting magnetic beads, followed by electrophoretic detection using 1.2% agarose gel.

Conclusion: In the classical 0.6X+0.2X volume ratio, 0.6X on one side can recover fragments of 400bp (inclusive) or more, while the double-sided 0.6X+0.2X can mainly recover fragments of 300-700bp.
