Notes
L-Lactate Assay Kit (ab169557) is suitable for measuring very low levels of L(+)-lactate in a variety of samples.
In this assay, L(+)-lactate is specifically oxidized to form an intermediate that reacts with a colorless probe to generate fluorescence (Ex/Em = 535/587 nm), which is directly proportional to the amount of lactate.
This simple, rapid and high-throughput suitable assay kit is the most sensitive lactate assay kit on the market. It can detect L(+)-lactate less than 0.2 uM in a variety of biological samples.
Other Notes
L(+)-Lactate is the major stereo-isomer of lactate formed in human intermediary metabolism and is present in blood. D(-)-Lactate is also present (see ) but only at about 1-5% of the concentration of L(+)-Lactate.

Supplementary info

- Activity summary
L-Lactate also known as lactate is a byproduct of anaerobic glycolysis where it plays an important role in energy metabolism. L-Lactate is a small molecule with a molecular mass of approximately 90.08 g/mol. It forms in various tissues like muscle cells during intense exercise when oxygen levels are low. This process leads to a conversion of pyruvate to lactate by the action of the enzyme lactate dehydrogenase (LDH) which is present in many tissues with higher expressions in muscles and heart.
- Biological function summary
L-Lactate acts as a signaling molecule which affects cellular functions and contributes to metabolic regulation. It is not part of a complex but serves as an important intermediate in metabolic pathways. L-Lactate provides energy to cells by converting back to pyruvate in the presence of oxygen which then enters the citric acid cycle. This conversion and its utilization as energy play important roles in balancing cellular energy demands especially under hypoxic conditions.
- Pathways
L-Lactate links to critical processes like glycolysis and the Cori cycle. During glycolysis pyruvate may convert to L-Lactate under anaerobic conditions to regenerate NAD+ necessary for glycolysis to continue. In the Cori cycle lactate produced by anaerobic glycolysis in muscles is released into the bloodstream and transported to the liver. There it converts back to glucose supporting gluconeogenesis. These processes highlight the close involvement of L-Lactate with proteins such as lactate dehydrogenase and pyruvate kinase.
- Associated diseases and disorders
L-Lactate is associated with conditions like lactic acidosis and cancer. Lactic acidosis characterized by high lactate levels can occur due to oxygen deprivation or mitochondrial dysfunction. Meanwhile cancer cells often show enhanced glycolysis and lactate production known as the Warburg effect facilitating their growth. Proteins like hypoxia-inducible factor 1-alpha (HIF-1α) and lactate dehydrogenase (LDH) are key players in these conditions influencing lactate metabolism and potentially serving as therapeutic targets.
