Wansadaj Jaroenram,Itthi Chatnuntawech,Jantana Kampeera,Sukanya Pengpanich,Pornsawan Leaungwutiwong,Benyatip Tondee,Sarawut Sirithammajak,Rapheephat Suvannakad,Pakapreud Khumwan,Sirintip Dangtip,Narong Arunrut,Sirasate Bantuchai,Wang Nguitragool,Suchawit Wongwaroran,Paisan Khanchaitit,Jetsumon Sattabongkot,Surat Teerapittayanon,Wansika Kiatpathomchai +17 more
TL;DR: In this article , a dual colorimetric RT-LAMP assay using in-house pH-dependent indicators was developed to maximize the visual detection and assay simplicity, and further integrated it with the artificial intelligence (AI) operated tool to enable a more precise and rapid result analysis in large scale testing.
Journal ArticleDOI
Identification of S315T mutation in katG gene using probe-free exclusive mismatch primers for a rapid diagnosis of isoniazid-resistant Mycobacterium tuberculosis by real-time loop-mediated isothermal amplification
