Abstract
A peptide compound for measuring sulfur compound and ammonia and measurement method and device using the compound. The method comprises contacting an analyte with a sensory device coated with the peptide compound to produce a signal, processing the signal to produce a result, and comparing the result with a database to define the presence of the sulfur compound and ammonia in the analyte.
Claims12
A peptide compound, comprising a peptide sequence of:
- Gly-Asn-Thr-Tyr-Asp,
- Glu-Gly-Asn-Thr-Tyr-Asp,
- Lys-Phe-Lys-Glu-Val,
- Glu-Ser-Lys-Val-Tyr,
- Asp-Val-Asn-Tyr-Gly-Asn, or
- Lys-Phe-Lys-Glu-Val-Thr-Arg-Glu-Asn.
A method for measuring sulfur compound and/or ammonia with a peptide compound, wherein the peptide compound comprises a peptide sequence of:
- Gly-Asn-Thr-Tyr-Asp,
- Glu-Gly-Asn-Thr-Tyr-Asp,
- Lys-Phe-Lys-Glu-Val,
- Glu-Ser-Lys-Val-Tyr,
