CUBICベースのタンパク質発現の可視化:全層マウス皮膚生検におけるタンパク質発現を可視化する手順

Executive Industry Relevance

Three-dimensional visualization of protein expression in intact skin biopsies addresses a critical need for spatially resolved, quantitative data in early discovery and target validation. The CUBIC-based protocol enables high-resolution mapping of protein markers in complex tissue architecture, supporting predictive confidence in disease-relevant models. This capability enhances translational continuity and de-risks mechanistic hypotheses in dermatological and tissue biology pipelines.
