The correct answer is Tata MD. Explanation & Key Takeaways: Omisure: • Omisure — India’s first home-grown testing kit — can differentiate the omicron strain of the novel coronavirus from the delta, alpha and the other variants in under four hours. • It is an omicron-detecting RT-PCR kit developed by the Mumbai-based Tata Medical and Diagnostics Ltd (TATA MD) in partnership with the Indian Council of Medical Research (ICMR). • The kit recently received approval from the Drugs Controller General of India. • It is a routine test like all other RT-PCRs did in the country. • Omisure can be a game-changer for detecting and controlling the Omicron variant because it can diagnose this variant in a single step. • This new kit can identify the Omicron variant by targeting two regions of the S or the spike gene. This gene codes for the spike protein, which helps the novel coronavirus enter and infect human cells. • The S, the Enveloped (E), and Nucleocapsid (N) genes are some of the targets of conventional RT-PCR tests. When it detects these genes, a patient sample is labelled positive.
