Application

Sodium L-lactate has been used:
  • as a medium supplement and cell fuel source for human mammary epithelial cell line(MCF10A) and dendritic cell culture
  • as a gluconeogenic substrate in hepatic glucose production assay in primary hepatocytes
  • in the glucose production medium for glucose production assay in human embryonic kidney (HEK293T) cells
  • as a standard for calibration in lactate assay in bone marrow-derived macrophages

Packaging

5, 10, 50 g in glass bottle

Biochem/physiol Actions

L-lactate is produced from pyruvate by the enzyme lactate dehydrogenase. Lactate production occurs during anaerobic glycolysis or in proliferatively active cells.

Articles
Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.
