Cutting-Edge Technology

Recombinase Aided Amplification Technology

Recombinase Aided Amplification (RAA) technology uses recombinase, single-stranded binding protein, and DNA polymerase under isothermal conditions (37–42℃) to amplify nucleic acids.
RAA overcomes the limitations of traditional PCR that relies on thermal cycling, offering advantages such as isothermal amplification, superior efficiency, high sensitivity and specificity, and user-friendly operation.
RAA aids QT BIO in developing a “more accurate, faster, and more convenient” biosecurity prevention and control system, in advancing molecular detection technologies, in building a comprehensive industry chain for biological prevention and control products, and in leading the upgrade of nucleic acid amplification technology towards “on-site detection and deskilling”.

Application Field

Zoonotic Disease Control

Zoonotic diseases refer to a category of illnesses naturally transmitted between animals and humans, caused by shared pathogens and epidemiologically linked. Zoonotic disease testing includes detection of Schistosoma japonicum, Cryptosporidium, Schistosoma mansoni, and others.

Food Safety

Food safety is a critical aspect of safeguarding public health, primarily involving the detection of microorganisms. Food safety testing includes detection of E. coli, Salmonella, Staphylococcus aureus, adenoviruses, and others.

Plant & Animal Quarantine

Animal diseases refer to infectious diseases in animals. Animal disease testing includes detection of pet pathogens, avian diseases, African swine fever, and others. Plant disease testing includes detection of pathogens such as Xylella fastidiosa, and others.

Healthcare System

Pathogens invade the human body through various routes, infecting different organs and leading to diseases. Human pathogen testing includes detection of pathogens causing febrile illnesses, infections, respiratory diseases, mycobacteria, enteroviruses, and others.

Literature Sharing: Establishment of Two Rapid RT-RAA Assays for H5 Subtype Avian Influenza Virus Detection

Avian influenza virus (AIV) poses a serious threat to the global poultry industry and public health, especially the highly pathogenic H5 subtype (H5-AIV). Between 2021 and 2022, the number of poultry deaths due to avian influenza exceeded 138 million, highlighting the urgent need to develop rapid detection technologies. Based on RT-RAA technology, this study developed two novel detection methods: RF-RT-RAA and RT-RAA-LFD, which can achieve rapid detection of H5-AIV within 15-30 minutes.
