Fig. 6From: Sensitive and selective detection of Mucin1 in pancreatic cancer using hybridization chain reaction with the assistance of Fe3O4@polydopamine nanocompositesFluorescence staining of tumor tissues implanted in nude mice by BxPC-3, PANC-1, Capan-1, or HepG-2 cells. Tissues were stained with Hoest33342 (A) and treated with Apt-random + H1-FAM/H2-FAM (B), Apt-Tri-FAM (C), or Apt-Tri-FAM + H1-FAM/H2-FAM (D), respectively. Scale bar = 20 µmBack to article page
