General description

Calcium Chloride (CaCl2) is a water soluble ionic crystal with a high enthalpy change of solution. It is majorly derived from limestone and is a by-product of the Solvay process. It is an anhydrous salt that has a hygroscopic nature and can be used as a desiccant.

Application

CaCl2 can be used for a variety of applications such as:
  • to decrease the freezing and to act as a de-icing agent
  • for the fabrication of an absorbent that can be used in solar absorption and dehumidification
  • can be mixed in concrete to provide a measure of the moisture

Packaging

10 g in ampule

Opsin, the rhodopsin apoprotein, was recently shown to be an ATP-independent flippase (or scramblase) that equilibrates phospholipids across photoreceptor disc membranes in mammalian retina, a process required for disc homoeostasis. Here we show that scrambling is a constitutive activity of...
