詳細

詳細

Sodium carbonate (Soda) is a white salt. It can be synthesized by the electrolysis of molten sodium hydroxide or sodium chloride.

アプリケーション

Sodium carbonate may be used for the determination of total polyphenolic index of wine products from grape by the Folin-Ciocalteu method. It has been used to compose the ELISA (Enzyme-Linked Immunosorbent Assay) coating buffer. It may be used to prepare the antibody coating buffer for use in IGF-I kinase receptor activation assay (KIRA) assay.
