Antibody validation
This commercial rabbit antibody from Abcam (ab210796) is a monoclonal antibody raised against a synthetic peptide derived sequence with 150 residues of the C-terminal region of the human claudin-7 protein. Our validation included staining of formalin-fixed, paraffin-embedded human duodenum, where the antibody decorated lateral membranes throughout the crypt-villus axis.
Immunostaining
