Vent TM DNA polymerase is a commonly used enzyme for PCR amplification. However, there are a few synonymous enzymes that can be used interchangeably with Vent TM DNA polymerase. For instance, Taq polymerase is another popular DNA polymerase that can be used for PCR amplification, and it is derived from the bacterium Thermus aquaticus. Another synonym for Vent TM DNA polymerase is Pwo DNA polymerase, which is similarly derived from Thermus aquaticus and is known for its high proofreading ability. Phusion DNA polymerase is another commonly used synonym for Vent TM DNA polymerase that is known for its high-fidelity amplification and its ability to amplify long fragments.
