Otimização, design e evitando armadilhas em manual multiplex fluorescente imuno-histoquímica

Overview

Multiplex fluorescent immunohistochemistry is a technique that allows for the visualization of multiple cell types in intact formalin-fixed, paraffin-embedded tissue. This method facilitates both cell identification and spatial analysis of cell interactions, particularly in the tumor microenvironment.
