The sbeadex Pathogen Nucleic Acid Purification Kit without dangerous goods and Proteinase K is a cutting-edge solution for fast and reliable isolation of highly purified DNA and RNA from various pathogenic bacteria, viruses and yeasts.

The sbeadex Technology

This kit leverages the power of sbeadex magnetic bead technology. These superparamagnetic particles, coated with sbeadex surface chemistry, employ a novel two-bind / two-wash mechanism that ensures effective removal of impurities from the sample matrix. The second wash buffer in the kit is ethanol-free, eliminating any traces of ethanol that could potentially inhibit downstream reactions. Additionally, the sbeadex technology eliminates the need for a drying step before elution, further enhancing DNA quality.

Figure 1:  Demonstration of no loss of RNA during the sbeadex Pathogen Nucleic Acid Purification Kit protocol.  500 copies of a 2019-COVID artificial RNA reference material were added to a sample (nasopharyngeal swab) and the sample processed with the sbeadex Pathogen Nucleic Acid Purification Kit. SARS-CoV-2 was detected in this preparation and a directly spiked positive control sample via a RT-qPCR at two separate Biosearch Technologies sites (reaction components described below). The concordant Cq values from both samples demonstrate no loss of sample due to the extraction step.

This kit does not contain Proteinase K.

This is a ready-to-use kit designed to streamline the DNA and RNA purification process, making it an ideal choice for downstream applications such as:

• PCR / qPCR

• Real Time (RT) PCR / qRT-PCR

• Next Generation Sequencing (NGS)

The kit is compatible with a wide range of automation platforms, such as Thermo's KingFisher and Hamilton's Microlab Star or our oKtopure, and can be easily automated on various liquid handlers and purification platforms. It offers high flexibility in reaction volumes, making it suitable for high-throughput purifications.

There are no dangerous goods within this kit ensuring an extra level of safety and regulatory compliance.
