FIG. 6.

Expression of the regulatory subunit 7 of protein phosphatase 1 (Sds22) in mice. (A to C) Immunoblot analysis of protein extracts derived from various wild-type mouse organs using polyclonal antibodies derived against N-terminal (A) or C-terminal (B) peptides of Sds22. (C) Immunoblot analysis of Sds22 protein expression in human and mouse testes derived from wild-type and Paskin knockout mice. (D) Indirect immunohistochemistry of testis cryosections with (Sds22) or without (control) an anti-Sds22 antibody. Original magnification, ×630. (C and D) The polyclonal antibody derived against the C terminus of Sds22 was used. Ab, antibody.
