Fig. 2. Immunolocalization of p35. (A) Control section incubated with antibody in the presence of blocking peptide. (B) Section incubated with p35 antibody, showing positive staining in the epithelium (single arrow) and the superficial, elongating fiber cells (double arrow), extending to the suture (arrowhead). (C) Higher magnification of the superficial, elongating fiber cells and overlying epithelial cells, showing staining along the basal side of the epithelial cells (single arrow) and the unstained capsule (arrowhead). (D) Posterior suture, where staining is substantially decreased. Bar, 250 µm (B,D); 125 µm (C).
