Web4.4. Adjusting the Incubation Temperature. Cross-reactivity may vary with temperature for two reasons. First, as explained above, cross-reactivity decreases with incubation time to a minimum at equilibrium. Since reaction rates increase with temperature, equilibrium is achieved more quickly at higher temperatures.
