Immunolocalization of BK Ca channel α- and β-subunit in non-pregnant myometrium. Positive staining for the α-subunit of BKCa (arrow) in (A) US myometrium and (B) LS myometrium. Positive staining for the β-subunit (arrow) in (C) US myometrium and (D) LS myometrium. (E-H) Negative controls. The primary antibody was substituted with (E) normal rabbit serum or (G) PBS. Sections were stained with (F) α-subunit preabsorption antibody or (H) β-subunit preabsorption antibody. Original magnification ×400.
