IRDye 650 Can Be Used for Immunohistochemistry

Immunofluorescence staining of HER2 protein on SK-BR-3 cells. Cells were cultured on cover slips. After fixation and permeabilization, cells were incubated with rabbit anti-HER2 mAb (CST), followed by detection with IRDye 650 Goat anti-Rabbit (P/N 926-65020). Nuclei were stained with DAPI. Image acquired with Olympus IX81 microscope.
