There is interference in serum samples due to precipitation. This issue can be greatly reduced by deproteinating with a filter, but some interference may still occur. This kit has not been validated for use with plasma samples or fecal samples. The reagent used in this kit reacts with urobilinogen, which is also excreted in feces. The kit would be unable to distinguish between indole and urobilinogen.

Can this kit be used with human serum, plasma, or fecal samples?

If the test assumes it's indoxyl sulfate, a high conc. say 80-90 um would indicate toxicity, considering its a uremic toxin? Higher ILA/IPA on other hand would mean a beneficial indole.
1 answer-
This kit is not intended to categorize a test sample as toxic. The test is designed to measure urinary Indican (Indoxyl sulfate) and assumes that most of the Indole in the sample exists as urinary Indican (Indoxyl sulfate). The test does not distinguish between Indole, Indican, or urinary Indican (Indoxyl sulfate), so it will likely detect other species such as Indolepyruvic acid, Indolelactic acid, and Indolepropionic acid if the reactive carbon is available. The test does not convert the indole derivative before the DMAB reaction.

Is any up front extraction of the biological sample necessary before running the assay (example: solvent extraction)?
1 answer-
The necessity for extraction often depends on the type of biological sample (e.g., serum, plasma, tissue, or cell lysates). Solid tissues may require extraction, while fluid samples may not.

Is this working in 560nm in microplate reader?
1 answer-
For optimal results, the plate should be read at 565 nm, as per the kit protocol.

Will this kit react with tryptophan alone. For example will it react in the presence of 100µM Trp?
1 answer-
This kit will detect and quantify indole only. Please consider alternate product MAK523 if the interest is in assaying tryptophan concentration. Please see the link below to review this product:

Does this kit only measure indole, or does it detect a wide variety of indole-containing compounds such as indolepyruvic acid, indolelactic acid, and indolepropionic acid?
1 answer-
The kit has not been tested with those compounds. The test is specifically designed to measure urinary indican (indoxyl sulfate), assuming that most of the indole in the sample exists as urinary indican (indoxyl sulfate).

Does this assay detect both indole and all its derivatives? Or is there a specificity towards some indoles?
1 answer-
Unfortunately, this kit has not been tested with Indole compounds such as indolepyruvic acid, indolelactic acid, and indolepropionic acid. The test is designed to measure urinary indican (indoxyl sulfate). It assumes that most of the indole in the sample exists as urinary indican (indoxyl sulfate). The test does not distinguish between indole, indican, or urinary indican (indoxyl sulfate) so it will likely pick up the species enumerated if the reactive carbon is available. The test does not convert the indole derivative before the DMAB reaction.
