Figure 6. Immunofluorescent staining with IL-1β specific antibody in corneal and conjunctival epithelia. Immunofluorescence staining with IL-1β specific antibody (red) in corneal epithelia (CE: arrows) and conjunctival epithelia (CJE: arrow heads) at all time points. The staining for IL-1β localized in CE and CJE was strong in BTX-B injected mice. Nuclear staining in blue. (F-J) and (P-T) merged pictures. Images of isotype and negative control were omitted with no staining. Scale bar: 50 μm.
