Application
Sodium L-lactate has been used:
- as a medium supplement and cell fuel source for human mammary epithelial cell line(MCF10A)[1] and dendritic cell culture[2]
- as a gluconeogenic substrate in hepatic glucose production assay in primary hepatocytes[3]
- in the glucose production medium for glucose production assay in human embryonic kidney (HEK293T) cells[4]
- as a standard for calibration in lactate assay in bone marrow-derived macrophages[5]
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.[6]
Features and Benefits
Versatile and adaptable for a wide variety of laboratory and research applications
General description
Sodium L-lactate, an organic acid derived from L-lactic acid, naturally occurs in the body, contributing to pH regulation, acid-base equilibrium, and various physiological processes, including energy metabolism through the Cori cycle. Its versatile properties extend to antimicrobial action by creating an acidic environment that inhibits harmful bacterial growth. In metabolic pathways, Sodium L-lactate exhibits efficient conversion for energy production, potentially surpassing glucose uptake in certain instances, utilizing fatty acids as an alternative fuel source, and stimulating mitochondria for enhanced ATP production, indicating a role in optimizing cellular energy efficiency. Moreover, research suggests neuroprotective capabilities, safeguarding neuronal cells from high-fat diet-induced death and addressing potential links to obesity-related neurodegenerative issues.
This multifaceted nature of Sodium L-lactate positions it as a valuable molecule for research in cellular metabolism, neuroprotection, antimicrobial, and nutritional science, where its diverse properties, including efficient energy conversion, neuroprotective effects, and potent antimicrobial activity contribute to a deeper understanding across these scientific domains.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
