感染細胞内の宿主および病原体タンパク質を可視化するための二重標識免疫蛍光法

Executive Industry Relevance

Double-labeling immunofluorescence enables precise visualization of both host and pathogen proteins within infected cells, directly supporting mechanistic de-risking and target validation in infectious disease research. This capability enhances predictive confidence at the discovery stage by clarifying spatial protein interactions critical for host-pathogen biology. The method is strategically positioned for portfolio triage and early-stage decision-making in biopharma R&D focused on infectious agents.
