Efficient isolation of virus DNA/RNA is crucial for various molecular biology applications, including diagnostics, epidemiological studies, and viral genome sequencing. Here, we present a simplified and cost-effective method for the purification of virus DNA/RNA using the AffiPURE Maxi Purification Kit. This kit utilizes affinity chromatography principles to achieve high yields of pure virus nucleic acids from diverse sample types. The protocol outlined in this article provides detailed step-by-step instructions for the extraction of virus DNA/RNA, making it suitable for both novice and experienced researchers. Additionally, we discuss the performance and advantages of the AffiPURE Maxi Purification Kit compared to traditional methods.

Isolation of virus DNA/RNA from complex biological samples is a fundamental step in virology research and diagnostic applications. Traditional methods for virus nucleic acid extraction often involve labor-intensive procedures with multiple purification steps, which can lead to sample loss and contamination. Affinity chromatography-based purification kits offer a promising alternative by enabling selective binding of virus nucleic acids to solid-phase matrices. The AffiPURE Maxi Purification Kit utilizes this principle to provide a rapid and efficient method for virus DNA/RNA extraction.

Materials and Methods

The AffiPURE Maxi Purification Kit includes prepacked columns containing specialized affinity matrices designed to selectively bind virus nucleic acids. The purification procedure involves simple lysis of virus particles followed by binding, washing, and elution steps. Briefly, the sample is lysed using a lysis buffer provided in the kit, and the lysate is then applied to the affinity column. After thorough washing to remove impurities, the purified virus DNA/RNA is eluted using a low-salt elution buffer.
