The probes have a structure according to the general formulawhere R1-R4 independently are hydrogen hydroxyl, halogen, thiol, thioether, lower aliphatic, or lower alkoxy, x is an integer from 0 to 4, and each R5 independently is halogen, hydroxyl, thiol, thioether, lower aliphatic, or lower alkoxy. Embodiments of the disclosed probes are capable of undergoing condensation/cyclization reactions with cysteine and/or homocysteine. Cysteine and/or homocysteine can be selectively detected and identified by determining fluorescence emission of the probes at characteristic wavelengths."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluorescence detection of cysteine and homocysteine","description":"Embodiments of probes for selectively detecting compounds having a thiol group and an amino group, e.g., cysteine and/or homocysteine, are disclosed, along with methods and kits for detecting the comp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9709572","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
