用于筛选抗病毒化合物的病毒附着测定

Executive Industry Relevance

Screening for antiviral compounds at the viral attachment stage is critical for early de-risking of therapeutic hypotheses targeting entry mechanisms. Quantitative luciferase-based readouts enable high-confidence differentiation of compound effects, supporting robust go/no-go decisions in antiviral discovery portfolios. This assay positions teams to triage candidates before resource-intensive downstream validation.
