Summary
Homebrew enzyme production enables low-cost, accessible SARS-CoV-2 detection using reverse transcription - loop-mediated isothermal amplification (RT-LAMP). This approach significantly reduces costs and enhances diagnostic capabilities in resource-limited settings.
Area of Science:
- Molecular Biology
- Virology
- Biotechnology
Background:
- Reverse transcription - loop-mediated isothermal amplification (RT-LAMP) is a sensitive and specific method for SARS-CoV-2 detection.
- High reagent costs and cold chain requirements limit RT-LAMP accessibility in low-income regions.
- Homebrew enzyme and buffer preparation offers a potential solution to these limitations.
Conclusions:
- Local production of essential enzymes enables cost-effective RT-LAMP assays.
- This approach enhances diagnostic autonomy and capacity in resource-limited settings.
- The study provides protocols and DNA resources for replication of these low-cost diagnostics globally.
