Fig. 6. Both Clik1 and CLP-36 are expressed in adult testis. (A) Human
multiple-tissue northern blot filters containing the indicated mRNAs
(Clontech, no. 7760-1, 7766-1 and 7757-1) were probed with Clik1. The
positions of the 7.5 kb mRNA standards are indicated on the right. (B) Western
blot analysis from adult mouse testis extract with rabbit polyclonal CLP-36
antibody: total testis extract (lysate), anti-CLP-36 immunoprecipitate from
testis extract (IP,
-CLP-36) and blocked anti-CLP-36 immunoprecipitate
(IP, block). (C) Frozen adult mouse testis sections were fixed with ethanol
and stained with rabbit polyclonal anti-CLP-36 or with blocked anti-CLP-36
(inset). The white arrow indicates the peritubular contractile cells
surrounding the seminiferous tubuli, and the white arrowhead indicates the
elongating spermatids. Bar, 40 µm.
