Step-by-step explanation:
At temperatures above 56°C, proteins unfold, a process called denaturation. This can be useful for a variety of reasons, including opening changing a proteins shape for easier identification by a detection antibody.
Experiments run at the bench are carried out at about 20-25°C, or room temperature.
At room temperature, most reagents and cell cultures are stable although some reagents need to be protected from light, some experiments need to be performed in a hood to maintain sterility, and some assays need to take place within a humid chamber to prevent the experimental tissues or reagents from drying out.
When your protocol says, to “thaw to cells or a particular reagent”, use a water bath set to 37 °C for slow and even warming. Unless your protocol indicates further heating, be sure to remove your sample from the water bath as soon as the last ice fragment has melted.
If protocol indicates that “pre-warmed media” or other pre-warmed reagents should be used, a 37 °C water bath also is useful for keeping solutions at a constant, warm – but not hot -- temperature.
In order to keep your solutions free from contamination or dilution from the surrounding water, use a foam floating rack to thaw frozen aliquots of cells or to warm microliter volumes of solution. If a more secure tube holder is preferred, a metal rack can be used for this purpose as well.
