  • 製品の概要

    Abcam's Phenylalanine Assay Kit provides a quick, simple, accurate method for quantifying PHE in biological samples. In the assay, PHE is reductively deaminated with the simultaneous formation of NADH which reacts with our fluorescent probe to generate fluorescence at Ex/Em=535/587 nm. The assay is linear in the range from 0.1 to 1.0 nmol (2-20 µM) of Phenylalanine.

  • 特記事項

    L-Phenylalanine (PHE) is an electrically-neutral amino acid, one of the twenty common and one of the three aromatic amino acids used to biochemically form proteins. Phenylalanine uses the same active transport channel as tryptophan to cross the blood-brain barrier, and, in large quantities, interferes with the production of serotonin. Errors in PHE metabolism lead to phenylketonuria or PKU which can have dire consequences.

Question
Answer

Thank you for contacting us.
The enzyme used in the assay can react with tyrosine and methionine as well as
phenylalanine. Serum methionine concentrations are generally low enough to be
insignificant in this assay. Tyrosine concentrations may interfere. If tyrosine interference is a concern, add 5 μl tyrosinase to the samples and preincubate for 10 minutes before
performing the assay to remove tyrosine interference.

Answer

Thank youfor your inquiry.

Please excuse the delay in my answer. this kit was not tested in-house and I was in contact with the lab that tested it.

Unfortunately, actual data is proprietary information.

But I was assured that the kitis suitable for mouse samples.

We do not know of any publications using this kit at the moment, but will add them to the datasheet as soon as we know of any.

I would like to reassure you that ab83376 is guaranteed for mouse samples by our Abpromise guarantee:

I am sorry that I could not provide all the answers on this occasion and hope this information is nevertheless helpful.

Question
Answer

Vielen Dank für Ihren Anruf.

Der im Phenylalanin-AssayKit ab83376verwendete Fluoreszenzfarbstoff (pico-probe) unterliegt zwar demBetriebsgeheimnis; allerdings wird er letztendlich in Resorufin umgewandelt - also genau, wie Sie schon vermutet hatten.

Ich hoffe, dies hilft Ihnen weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Answer

Thank you for contacting Abcam. We have not tested if this kit can differentiate between the two forms of phenyl alanine, that does not mean it cannot, it just means that we cannot guaranteed that it will. If there is anything else I can help you with, please let me know.
