Description

Application

Sodium bicarbonate has been used as a supplement:

• in minimum essential medium (MEM)/flushing medium for embryo isolation
• in TCM 199 medium for the collection of cumulus-oocyte complexes (COCs) and in vitro maturation (IVM)
• in IVM medium for in vitro maturation of COCs

Biochem/physiol Actions

Sodium bicarbonate occurs naturally as the mineral nahcolite. It is used to prepare many sodium salts as well as a carbon dioxide source. Sodium bicarbonate is used in the manufacture of fire extinguishers and cleaning agents. Bicarbonate plays an important role in pH regulation in vivo. In biochemistry, molecular biology, and chromatography, sodium bicarbonate is used as a buffer. This Hybri-Max^™ product is suitable for use in hybridoma and cell culture research (2.2 mg/ml).
