The melting point, T eq, of LM agarose is about 10 oC lower than the HM agarose. Thus when quenched to the same temperature, T, the induction time for LM agarose must be larger than for HM agarose of same concentration. This can be observed for both 0.5% and 1% concentrations.

WebThe melting temperature of a gel is the temperature above which it will unset and become a liquid again. For example, gelatin tends to melt at a hot picnic while agar can be heated up to 80°C (176°F) before it begins to melt. Not all gels have a melting temperature, such as thermo-irreversible gels which never melt.
