产品说明
一般描述
Sodium carbonate (Soda) is a white salt. It can be synthesized by the electrolysis of molten sodium hydroxide or sodium chloride.
应用
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.
生化/生理作用
缓冲剂组分，可用于除去外周膜蛋白。
