(a) SDS-PAGE analysis of the equilibrated solution from mineralization hydrogel shows the band of 22k of full-length amelogenin rP172 and a big band of 43k of rP172 dimer. (b) HPLC-MS chromatograph peak of the equilibrated solution from the mineralization hydrogel and (c) corresponding MS spectrum of the protein at 21.2–23.0 min shows the intact molecular weight of rP172. The peak at 25 min impurity is from agar hydrogel.

SDS-PAGE: sodium dodecyl sulfate–polyacrylamide gel electrophoresis; HPLC-MS: high-performance liquid chromatography-mass spectrometry.
