... tested. Interestingly, in contrast to mature BMP-2, proBMP-2 did not lead to induction of AP. Instead, proBMP-2 inhibited the induction of AP by BMP-2. This result raised the question of whether ... the area bound by the antagonist noggin [32], we attempted to verify these findings by testing the binding of proBMP-2 to noggin. Biotinylated noggin was immo- bilized on streptavid...
