Calcium (Ca)
Elemental calcium was discovered in 1808. This alkaline earth metal is the fifth most abundant in the Earth's crust and is found in leaves, bones, teeth, and shells.
Never found uncombined in nature, it can occur as limestone, gypsum, and fluorite. The rather hard metal has a silvery color, forms a white coating in air, reacts with water, and burns with a yellow-red flame.
Both natural and prepared compounds are widely used. Calcium oxide, when mixed with sand, hardens mortar and plaster, and calcium from limestone is a key ingredient in Portland cement. Other important compounds are carbide, chloride, cyanamide, hypochlorite, nitrate, and sulfide.

Apexbio Technology LLC Calcium Phosphate Cell Transfection Kit 200T
Calcium phosphate transfection is a commonly used method for introducing exogenous DNA into eukaryotic cells DNA-calcium phosphate precipitate adheres to cells by interacting with their cell surface The exogenous DNA is subsequently internalized via cellular endocytosis ultimately delivering the DNA into target cells This method has been successfully applied to various cell lines to achieve transient or stable transfections HEK293 cells are most suitable for calcium phosphate transfection Hela and CHO cells can also be transfected using the calcium phosphate method with slightly lower transfection efficiency This product significantly enhancing transfection efficiency and reducing cytotoxicity Additionally the kit provides highly consistent pH values and salt concentrations ensuring reliable transfection efficiency across different experiments and meet for the transfection needs of most adherent and suspension cells
