Molecular Probes Fibronectin Strain Lung Tissue (IMAGE) Georgia Institute of Technology Caption Staining of fibronectin-targeting molecular probes displays the LNLPHG (blue) and RFSAFY (red) peptide sequences on prepared living lung slices. The probes did not attach to the same fiber, which confirmed their ability to selectively discriminate strained or relaxed regions within a fibronectin fiber network.
