Application
Calcium chloride dihydrate has been used for synthesis of chemical hydrogels based on telechelic Poly (vinyl alcohol) (PVA). It has also been used for investigating the morphology of polystyrene-based emulsion-templated (PolyHIPE) materials.
Biochem/physiol Actions
Calcium chloride act as precipitants during protein crystallization process. It also enhances the competence of Escherichia coli cells as well as strengthened β-lactoglobulin gels by forming crossbridges.

Escherichia coli cells are 4--6 times more transformable and 20--30 times more competent after 24 h incubation in cold calcium chloride than immediately after calcium chloride treatment. With 24-h-old competent cells we obtained routinely 2 . 10(7) transformants per microgram

Protein crystallization is a major bottleneck in protein X-ray crystallography, the workhorse of most structural proteomics projects. Because the principles that govern protein crystallization are too poorly understood to allow them to be used in a strongly predictive sense, the
