AI Technical Summary
Existing technologies for varicella-zoster virus (VZV) detection suffer from problems such as long detection cycles, low sensitivity, high equipment requirements, complex operation, high detection costs, poor reaction system stability, and high non-specific amplification rates, making it difficult to meet the rapid and sensitive detection needs of primary healthcare institutions and home self-testing.
The LAMP-CRISPR combined detection method was adopted. By designing a carefully crafted LAMP primer set and crRNA, and combining the LAMP reaction system lyophilized microspheres and the CRISPR detection system lyophilized powder, a single-tube one-step detection method was achieved. The LAMP primer set was used to specifically amplify the VZV ORF62 gene, and the detection was performed with high sensitivity using the CRISPR/Cas12a system. A nucleic acid release agent was added to efficiently release viral nucleic acid.
It achieves rapid, sensitive, and highly specific VZV detection, with a detection time as fast as 35 minutes. It requires no complicated equipment and is suitable for primary healthcare institutions and home self-testing. The detection limit is as low as 100 copies/μL, which can effectively detect low viral load samples during the latent infection period.
