•Cyt b gene a potential molecular tool to identify Cow leathers.•Primers and probes designed are unique and specific.•Low levels of mtDNA extracted from finished cow leathers facilitate PCR amplification. Authentication of true (genuine) cow leathers is in high demand to promote merchandise and economic growth. The present study employs RT-PCR-based TaqMan assay to facilitate the identification. Species-specific primers and probes were designed utilizing the existing NCBI data on mitochondrial DNA (mtDNA) genes, particularly the cytochrome b region (Cyt b). Mitochondrial DNA extracted from leather samples of both Bos taurus and Bos indicus and analyzed following the appropriate procedures. The RT-PCR results showed the designed primers and probes are exceptionally precise for cow leather samples. The established detection limit for the assay is estimated as 0.1 ng of DNA. In summary, the amplifiable mtDNA extracted from finished leather enables the identification of authentic cow leathers using the RT-PCR TaqMan assay, representing a pioneering report in this field.
