Quality Level 200 
SMILES string O.O.Cl[Ca]Cl
solubility H2O: 294 mg/mL, clear, colorless
Application: Calcium chloride dihydrate has been used:
to prepare competent E. coli for transformation(118)
in the preparation of calcium polyphosphate nanospheres and to induce alkaline phosphatase(119)
as a component of renaturation buffer for the zymogram of Staphylococcus aureus crude enzyme extracts(120)
Biochem/physiol Actions: Calcium chloride is used in the heat-shock transformation of microbes with the plasmid. The positive charged calcium forms a cation bridge with phosphate of DNA and negative charged phosphorylated lipid A in lipopolysaccharide (LPS) aiding the DNA transformation into the microbes.
