Taq DNA Polymerase: sc-43501

Taq DNA Polymerase, derived from the thermophilic bacterium *Thermus aquaticus*, is a critical enzyme in molecular biology research due to its central role in the polymerase chain reaction (PCR), a technique used to amplify small segments of DNA. This enzyme is particularly valuable because of its ability to withstand the high temperatures associated with the denaturing phase of PCR, typically around 94°C to 96°C, without losing its activity. During PCR, Taq DNA Polymerase synthesizes new strands of DNA by adding nucleotides to a DNA template in a sequence-specific manner, beginning at the site of short DNA fragments known as primers. Its optimal activity at temperatures between 75°C and 80°C, combined with its rapid action in extending DNA strands, makes it ideal for the repetitive heating and cooling cycles of PCR. This capability has transformed genetic research, enabling rapid and efficient DNA cloning, sequencing, and analysis across various applications, from forensic science to evolutionary biology. Despite its lack of proofreading ability, which can lead to errors in DNA replication, Taq DNA Polymerase remains a fundamental tool in laboratories worldwide, facilitating the detailed study of genetic material in a manner that was not possible before its adoption.
