简介：
Overview
The dot assay is a two-dimensional, unconstrained migration assay designed to evaluate the migratory phenotype of attached, cohesive cell sheets in response to microenvironmental cues. This method is particularly useful in cancer research for understanding how various factors influence tumor cell motility.
Key Study Components
Area of Science
