About Lactic Acid

Lactic acid is a carboxylic acid with a molecular formula of C3H6O3 and contains a hydroxyl group. It belongs to α-hydroxy acid (AHA).

The production process of lactic acid is: pyruvate+NADH+H+→lactic acid+NAD++2H

Lactic acid is widely used as preservatives, carriers, co-solvents, pharmaceutical preparations, pH regulators, etc.

Lactic acid has three configurations, namely L-type, D-type and DL-type. Its CAS registration numbers are 79-33-4 (L), 10326-41-7 (D), and 50-21-5 (DL).
MS-based technical means can realize the qualitative and quantitative analysis of lactic acid.

Sample Requirements

Sample type
Plants, yeasts, microorganisms, etc.
Serum, plasma, urine, bile, bile acid, etc.
Cells, liver, brain tissue and other animal tissues and feces, etc.
There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information.
Sample demand
Plant root / stem / leaf / fruit / seed > 200 mg fresh weight, freeze-dried sample > 0.5 g
Cells / microorganisms / cell supernatant / culture medium supernatant: the number of cells or bacteria > 107, supernatant > 2 ml
Serum / plasma / urine / ruminal fluid / cerebrospinal fluid / amniotic fluid and other homogeneous liquid samples > 200 µl.
(Hemolysis should be avoided. Cerebrospinal fluid can be as low as 100 µl.)
Animal tissue / feces related samples > 200 mg / sample
For other sample types, please consult technical support or sales.
Sample mixed and repeat
In order to ensure the accuracy of the samples and reduce systematic errors during sampling, it is necessary to select more than 3 materials with the same condition for each sample.
※ The same condition refers to the same period, basically the same phenotype, and the same part.
It is recommended that prepare more than 6 biological replicates.
Storage and transportation
Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature, and store it at -80°C.
Dry ice transportation (about 3~4 kg dry ice is consumed every day, please use sufficient dry ice for transportation).
