Webenzymatic activity assays. Different detergents may also have different optimal temperatures for enzyme activity; therefore, a preliminary temperature test must be devel-oped to determine the temperature range that should be tested in further analyses. For the biological samples, 1–2 mL of saliva from each student is needed. WebThe temperature ranges over which enzymes show activity is limited between the melting point (O degree celcius) and boiling point (100 degree celcius) of water. If the temperature is too low, there can be no noticeable reaction rate since the enzyme is operating at a temperature too below its optimum. WebEnzymatic properties. Taq's optimum temperature for activity is 75–80 °C, with a half-life of greater than 2 hours at 92.5 °C, 40 minutes at 95 °C and 9 minutes at 97.5 °C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72 °C. onpl charlot
