Applications Notes

CheKine™ Micro Lactate Assay Kit provides a convenient means for detecting L (+) -Lactate in biological samples such as in serum or plasma, cells, culture and fermentation media. In this kit lactate is oxidized by lactate dehydrogenase to generate a product which interacts with a tetrazolium salt WST-8 dye to form a colorimetric (450 nm) product, proportional to the lactate present.

Product Properties

Kit Components

• Lactate Assay Buffer
• Lactate Dehydrogenase
• Lactate Dehydrogenase Cofactor
• WST-8
• Enhancer
• L (+) -Lactate Standard  (100 mM)

Features & Benefits

• Determination of L (+) -Lactate in serum, plasma, cell/tissue samples, plant tissues, urine and other biological fluids.
• Detect biological samples at a level of 0.03 mM-2 mM.
• Pre-treatment or purification of samples are not required.
• Using WST-8 as substrate, more sensitive than MTT.

Usage Notes

• If not assayed immediately, samples can be stored at -80°C for one month.
• It is recommended to perform several dilutions of your sample to ensure the readings are within the standard value range.
• Fresh samples are necessary for good results. If  don’t perform the assay at the same time, it’s better to complete the Sample Preparation step before storing the samples.

Storage Instructions

Storage at -20°C and Keep from light immediately upon receipt. Kit has a storage time of 6 months from receipt. Refer to list of materials supplied for storage conditions of individual components.
