Selection of Novel Peptides Homing the 4T1 CELL Line: Exploring Alternative Targets for Triple Negative Breast Cancer - Fig 3

<p>Immunofluorescence staining of 4T1 (A-C) and MDA-MB-231 (D-E) tissues with 4T1pep1 and 4T1pep2. (A1-A3) 4T1 tissue section incubated with wild-type M13 phage (negative control). (B1-B3) 4T1 tissue section incubated with M13 phage displaying 4T1pep1, stained with DAPI (B1) and FITC (B2). (C1-C3) 4T1 tissue section incubated with M13 phage displaying 4T1pep2, stained with DAPI (C1) and FITC (C2). (D1-D3) MDA-MB-231 tissue section incubated with wild-type M13 phage (negative control). (E1-E3) MDA-MB-231 tissue section incubated with M13 phage displaying 4T1pep1, stained with DAPI (E1) and FITC (E2). (F1-F3) MDA-MB-231 tissue section incubated with M13 phage displaying 4T1pep2, stained with DAPI (F1) and FITC (F2).
