From: Expression of carbonic anhydrases IX and XII during mouse embryonic development
Immunostaining of CA IX and CA XII in embryonic and adult mouse nervous tissues. All embryos are aged E12.5 except the choroid plexus for CA XII, which is aged E13.5. CA IX shows moderate staining in the embryonic brain (A), with the signal mainly located in the neurons. CA IX is also present in the trigeminal ganglion (B) and the choroid plexus (C). Panel G shows strong positive staining for CA IX in the adult brain. CA XII gives weak staining in the embryonic brain (D), but panel E shows moderate staining in the trigeminal ganglion. The strongest immunoreaction is located in the chroid plexus (F). No specific signal for CA XII is detectable in the adult brain (H) except for the choroid plexus (data not shown). Control immunostaining of the embryonic brain with normal rabbit serum is negative (I). Manual PAP staining in panels A-E and I, automated immunostaining in panels F-H. Original magnifications: A-E, I × 400, F × 630, G-H × 200.
