  • 製品の概要

    Lactate Dehydrogenase (LDH) Assay Kit (Colorimetric) (ab102526) quantifies LDH activity in a variety of biological samples such as serum or plasma, cells, culture medium and fermentation. In this assay LDH reduces NAD to NADH, which then interacts with a specific probe to produce a color (OD max = 450 nm). The kit can detect 1 - 100 mU/mL of LDH directly in samples. The assay is quick, convenient, and sensitive.

  • 特記事項

    As LDH is a fairly stable enzyme, LDH has been widely used to evaluate the presence of damage and toxicity of tissue and cells. Quantification of LDH has broad range of applications. The kit can detect 1-100 mU/ml of LDH directly in samples.

  • 関連性Lactate dehydrogenase (LDH) is an oxidoreductase which catalyses the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+. As it can also catalyze the oxidation of hydroxybutyrate, it is occasionally called Hydroxybutyrate Dehydrogenase (HBD). There are 5 different isoenzymes of LDH, LDH1 to LDH5, each composed of 4 subunits which may be of 2 different types - M and H subunits. These subunits are encoded by two different genes: The M subunit is encoded by gene LDHA whilst the H subunit is encoded by LDHB. Usually LDH2 is the predominant form in the serum. An LDH1 level higher than the LDH2 level suggests myocardial infarction (damage to heart tissues releases heart LDH, which is rich in LDH1, into the bloodstream).

The kit ab102526 is more suitable for measuring the LDH activity in tissue culture supernatants - It can also be used for tissue extracts.

ab65393 is only tested with cells and cell extracts - tissue extracts are yet to be tested therefore I ...

Based on the info you sent you basically diluted 1:10 once witht he original supernatant and then 1:10 again by using 5 ul plus assay buffer to make 50 ul total, so your final dilution is 1:100. Please let me know if you have any further que...

The dilution is the initial sample dilution. If you have 10 µl of a sample and are diluting it 100 times and then taking in 5 µl from that diluted sample into the well, your dilution factor would be 100. In this case dilution would be 1 since you ...

Thank you for contacting us.

The two vials are actually lysophilized products. It does not say this on the datasheet, however the protocol booklet itself (which should have come with the kit and can also be downloaded from our website) gives...

Thanks for your enquiry regarding ab102526.

We have no specific recommendations for what kind of media you could use with this assay. I just looked it up online and it looks like phenol containing medium having ˜10% FBS will enhance the signa...

There is a possibility that the PR in the media might interfere to some extent. To account for such interference, I would recommend using a control sample with just the plain media in replicate wells. Any signals due to any components in the media can ...
