    Abcam's D-Lactate Assay Kit (Colorimetric)Kit provides a fast, easy way to accurately measure D-lactate in a variety of biological samples. In this kit, D-lactate is specifically oxidized by D-lactate dehydrogenase and generates proportional color (?max = 450 nm). The kit detects D-Lactate in samples such as serum, plasma, cells, culture and fermentation media.

  • D-Lactate measured in human serum, plasma and saliva, mouse serum and plasma and fresh yoghurt showing quantity (nmol) per ml of tested sample. Samples were diluted 3-27 fold.

  • Colorimetric standard curve: mean of duplicates (+/- SD) with background reads subtracted.
  • D-Lactate Standard Curve. The assay is performed according to the kit instruction. The assay specifically detects D-Lactate in the presence of up to 1000X L-Lactate.
  • Standard curve: mean of duplicates (+/- SD) with background reads subtracted.
  • Measurement of plasma D-lactate at 24h and 48h after ANP induction using ab83429.

    To evaluate the severity of intestinal barrier dysfunction, plasma DAO and D-lactate were measured as indicators of intestinal mucosal mass and integrity which can reflect the extent of permeability and damage in the intestine.

    Compared with the SO groups D-lactate significantly increased in the ANP groups at 24h and 48h (all p<0.05). The ANP48h group had significantly higher levels of plasma D-lactate than those of the ANP24h group (p<0.05, respectively).

Thank you for contacting us. Yes, D-lactate is produced in very low levels in mammals unless there are certain bacterial infections or trauma. L(+)-Lactate is the major stereoisomer of lactate formed in human intermediary metabolism and is present in b...

Urine samples would also have NADH. Therefore, the background control step should be run.
Since NADH is one of the reaction intermediates in this assay, we want to make certain that any readings we see are due to the assay reaction of D-Lactate co...

Besides completely depressing the plunger on the pipette tip, the lab suggested also the following:

In addition, the customer can try to point the pipette tip towards the side walls of the wells instead of the bottom. That way the bubbles...

Thank you for your enquiry regarding ab83429.

As long as the band width of detection on the instrument says ± 50, you can use 500 nm instead of 450 nm. Otherwise it will compromise the efficiency of the assay.

I hope this hel...

Please let the Dr B. know the following:

You can directly use different doses of serum/plasma with this assay. Just make up the volume in the wells to 50 µl with the assay buffer.

All readings have to be made at 450 nm. Pleas...

I am not familiar with the contents of MRSB media, but in general cell culture supernatants will be compatible with these kits. If the media contains serum, we recommend deproteinizing the samples using our 10 kDa...

Thank you for your inquiry.

1.) I can confirm that urine should be centrifuged for 30 minutes at 1500g. Then the samples should be stored at -80C and / orde- proteinised with ab93349 (10kD spin column).

Thank you for your inquiry.

I am not personally familiar with the Roche Cobas C501, however this is a colorimetric assay, so as long as your plate reader measures at 450 nM, it should be fine.
