Automatic polymerase chain reaction product detection system for food safety monitoring using zinc finger protein fused to luciferase.

An automatic polymerase chain reaction (PCR) product detection system for food safety monitoring using zinc finger (ZF) protein fused to luciferase was developed. ZF protein fused to luciferase specifically binds to target double stranded DNA sequence and has luciferase enzymatic activity. Therefore, PCR products that comprise ZF protein recognition sequence can be detected by measuring the luciferase activity of the fusion protein.

Detection of pathogenic bacteria by using zinc finger protein fused with firefly luciferase.

We constructed a novel bacterial genome detection system using zinc finger protein (ZF) fused with firefly luciferase (ZF-luciferase). Taking advantage of the direct recognition of double-stranded DNA (dsDNA) by ZF, we previously constructed bacterial genome detection systems that did not require dehybridization processes. To detect polymerase chain reaction (PCR) products rapidly and with a high sensitivity, we constructed two kinds of ZF-luciferase, Sp1-fused luciferase (Sp1-luciferase), and Zif268-fused luciferase (Zif268-luciferase).

Zn finger-based direct detection system for PCR products of Salmonella spp. and the Influenza A virus.

We have detected PCR products from Salmonella spp. and Influenza A virus using Zn finger protein Zif268 and Sp1, respectively. Previously, we demonstrated a novel method of rapid and specific detection of PCR products from Legionella pneumophila genome using Zn finger protein Sp1.

Zinc finger protein-based detection system of PCR products for pathogen diagnosis.

A novel detection system of PCR products from bacterial genomes using Zinc finger proteins was developed. Zinc finger proteins are DNA-binding proteins that can bind to dsDNA with high affinity and specificity. Since Zinc finger proteins can directly detect PCR products and can double-check the specific PCR amplification and sequence specificity of the PCR products, this novel method would be quick and highly accurate.

The simple and rapid detection of specific PCR products from bacterial genomes using Zn finger proteins.

A novel method of rapid and specific detection of polymerase chain reaction (PCR) products from bacterial genomes using Zn finger proteins was developed. Zn finger proteins are DNA-binding proteins that can sequence specifically recognize PCR products. Since Zn finger proteins can directly detect PCR products without undergoing dehybridization, unlike probe DNA, and can double check the specific PCR amplification and sequence specificity of the PCR products, this novel method would be quick and highly accurate.

Specific detection of PCR product from Legionella pneumophila strain Philadelphia1 using zinc finger protein Sp2.

We have developed a novel method to detect PCR products from pathogen genome DNA by Zinc finger protein that can bind to double strand DNA (dsDNA) in sequence specific manner. In this study, we tried to detect Legionella pneumophila strain Philadelphia 1 using Zinc finger protein. We found the specific target DNA sequence for zinc finger protein Sp2 in L.
