Background Introduction

With the rapid development of molecular biology, molecular diagnosis and detection technologies represented by nucleic acid hybridization, nucleic acid amplification, and nucleic acid sequence analysis have received widespread attention. One of the most critical aspects of molecular diagnostic experiments is sample processing, which serves as the "first step" in the workflow. The efficiency and accuracy of this initial stage are paramount, as the quality of the nucleic acids extracted directly determines the success or failure of downstream molecular biology experiments. High-quality nucleic acid samples ensure reliable results in subsequent procedures such as polymerase chain reaction (PCR), sequencing, and other analytical techniques. Conversely, poor-quality samples can lead to inaccurate data, failed experiments, and potentially erroneous conclusions. Building on this foundation, Alfa Chemistry has developed silica carboxyl magnetic beads specifically for nucleic acid extraction and purification.

Our Products

The silica carboxyl magnetic beads provided by Alfa Chemistry are specially designed for nucleic acid extraction and purification. They not only have good suspension properties, but also a large number of carboxyl groups are modified on the surface. These magnetic beads can specifically bind to nucleic acids in solution through hydrophobic effect, hydrogen bonding and electrostatic interaction under high salt and low pH conditions, without binding to other impurities (such as proteins), thus rapidly separating nucleic acids from biological samples. Our products are safe and simple to operate and facilitate automated and high-throughput extraction of nucleic acids.

Advantages

Our products have superparamagnetism and high magnetic responsiveness, which can significantly save operation time.
Our products have good dispersibility and resuspension, which facilitates efficient combination and recovery of nucleic acids.
Our products have good physical and chemical stability to ensure repeatability.

You Need to Know

Do not freeze, dry, or centrifuge our products. These operations will cause the beads to agglomerate, making them difficult to resuspend and disperse, and will affect the chemical activity of the surface functional groups on the beads.
Before using our products, make sure to thoroughly oscillate or ultrasonic to maintain a uniform suspension of the beads.
Our products need to be used with magnetic separation equipment.
Our products are for research use only.
