  • Product overview

    Picoprobe 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 µM in a variety of biological samples.

  • Notes

    Lactate (CH3CH(OH)COO-) plays an important role in many biological processes. Abnormally high concentrations of lactate have been related to diseases such as diabetes, lactic acidosis, etc. L(+)-Lactate is present in blood and is the major lactate stereoisomer formed in human intermediary metabolism. D-Lactate is also present but only at about 1-5% of L(+)-Lactate concentration. Lactate is a significant energy source for living organisms and can be used to generate cellular ATP.

  • Relevance
    Lactate (CH3CH(OH)COO-) plays important roles in many biological processes. Abnormal high concentration of lactate has been related to disease states such as diabetes and lactate acidosis, etc. L(+)-Lactate is the major stereoisomer of lactate formed in human intermediary metabolism and is present in blood. The lactate to pyruvate ratio reflects the redox state of the cell and describes the balance beween NAD+ and NADH, which is dependent on the interconversion of lactate and pyruvate via lactate dehydrogenase (LDH).

Lactate assay on HK-2 cells

 Average Good 4/5 (Ease of Use)
Abreviews
I've used this kit to measure Lactate levels in both cells and supernatant.
Cells:
0.5*10^6 cells were sonicated in assay buffer. 10ul from the lysate were loaded on assay wells. readings were about 10 times higher than the highest value of standard curve. further dilution is needed.
Medium:
10ul were loaded directly to assay well (without de-proteinization).
again, values were much higher than standard curve assay and had to be diluted.

Over all, kit was fairly OK and produced reasonable data.

section 6B part 2 of the protocol, "sample preparation" suggests using percholic acid/KOH protocol - can you please send me the detailed protocol for this step?
