Catalog No. C0222 Copy Product Info
🥰Excellent
TargetMol silica magnetic beads are specially designed for nucleic acid extraction and purification. The bead surface is composed of high-purity silica material enriched with silanol groups (hydroxyl groups) or carboxyl groups, which enable efficient and specific binding to nucleic acid molecules through hydrophobic interactions, hydrogen bonding, and electrostatic interactions under high-salt and low-pH conditions, while exhibiting minimal adsorption to impurities such as proteins. This allows rapid separation and purification of nucleic acids from complex biological samples.
The product features a simple workflow and high operational safety, and is suitable for both manual operation and automated platforms, particularly for high-throughput nucleic acid extraction applications.

Handling Instruction | TargetMol Precautions

1.Avoid freezing, drying, or high-speed centrifugation of the magnetic beads.

2.To minimize bead loss, the magnetic separation time should not be less than 1 min each time.

3.Before removing beads from the storage container, mix thoroughly to ensure uniform suspension. Avoid bubble formation during operation.

4.High-quality pipette tips and reaction tubes are recommended to minimize loss caused by bead and solution adhesion.

5.This product is intended for professional scientific research use only. It must not be used for clinical diagnosis or treatment, food or drug applications, and must not be stored in residential environments.

6.For your safety and health, please wear a lab coat and disposable gloves during operation.
