| Application: | Calcium carbonate buffer has been used as a component of alginate solution for tissue culture, and for preparing conductive alginate-coated electrodes. It has also been used in the preparation of alginate hydrogel for drug delivery. |
| Biochem/physiol Actions: | Calcium carbonate aids in bone formation and mineralization. It is often used as an antacid due to its potent alkalizing properties. Calcium carbonate has good biocompatibility, porous structure, large surface area, and high loading capacity. These properties of calcium carbonate make it favorable to use as a drug delivery system. In addition, the lower solubility of calcium carbonate (CaCO3) makes it effective in reducing the gelation rate and prolonging the working time for alginate gels. Therefore, it is widely used in the preparation of alginate solution. |
| Features and Benefits: | • BioReagent grade. • High level of assay ( ≥99.0%), indicating its purity. • Designed for insect cell culture applications. |
| General description: | Calcium carbonate (CaCO3) is a ternary ionic compound formed by carbon, oxygen, and calcium. It is one of the most common minerals found in rocks worldwide. It aids in studying the process of biomineralization, where it participates in the formation of various mineral structures including marine sediments, shells of marine organisms, snails, coal balls, pearls, and eggshells. CaCO3 exists in different mineral forms such as calcite, aragonite, and vaterite. |
