The compositions include, for example, a compound of formula R1—C(X)—NR2R3, wherein R1 is alkyl, haloalkyl, hydroxyalkyl, amino, or alkylamino, X is O or S, and R2 and R3 are independently H, alkyl, or hydroxyalkyl, a salt thereof, or a combination thereof, and at least one non-ionic density gradient medium. Also disclosed are methods for clearing tissue comprising positioning a tissue in a tissue clearing composition and allowing a tissue clearing composition to permeate the tissue. Further disclosed are methods for visualizing tissue characteristics which involve fixing a tissue, staining the tissue, positioning the tissue in the tissue clearing composition and allowing the tissue clearing composition to permeate the tissue, and imaging the tissue utilizing a microscope or tissue scanning device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and composition for optical clearing of tissues","description":"Disclosed are compositions, methods, and kits for clearing tissue that preserve cellular morphology, reporter fluorescence, and epitope labeling which allow for quantitative phenotypic analysis of int","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11480502","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.
