The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

Freezing Cells Dmso The methods for freezing-down HEK 293 cell lines are as follows: NOTE: The common practice up to this point has been to freeze-down one to two confluent 60-mm TC dishes (p60) of HEK 293 cells per cryovial. This protocol follows with that in mind. 1. Aspirate the medium from the confluent TC plate(s), keeping in
