WebNov 7, 2000 · The decrease in Rubisco activation occurred when leaf temperatures exceeded 35°C, whereas the activities of isolated activase and Rubisco were highest at … WebA simple formula for calculation of the Tmis Tm= 4(G + C) + 2(A + T)°C. Thus, the annealing temperature chosen for a PCR depends directly on length and composition of the primer(s). One should aim at using an annealing temperature (Ta) about 5°C below the lowest Tmof the pair of primers to be used.
