The labeling reagents comprise monovalent antibody fragments or non-antibody monomeric proteins whereby the labeling proteins have affinity for a specific region of the target-binding antibody and are covalently attached to a label. Discrete subsets of labeling reagent and immune-labeled complexes are provided that facilitate the simultaneous detection of multiple targets in a sample-complexes are distinguished by i) a ratio of label to labeling reagent, or ii) a physical property of said label, or iii) a ratio of labeling reagent to said target-binding antibody, or iv) by said target-binding antibody. This is particularly useful for fluorophore labels that can be attached to labeling reagents and subsequently immuno-labeled complexes in ratios for the detection of multiple targets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antibody complexes and methods for immunolabeling","description":"Provided are labeling reagents and methods for labeling primary antibodies and for detecting a target in a sample using an immuno-labeled complex that comprises a target-binding antibody and one or mo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8535894","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.
