Western blot analysis of δ₁ and δ₂ protein expression in Xenopus pituitary. Similar amounts of protein from NILs and ALs of black (B)- and white (W)-adapted Xenopus were resolved by SDS-PAGE and immunoblotted with either anti-RH6 (δ₁) or anti-1262N (δ₂). To correct for loading, actin protein levels were also determined. Data shown are the means (±SEM) of three independent experiments with NIL of black-adapted Xenopus as 100%.
