Article: New biological chemistry study findings recently were reported by researchers at Northwestern University.

"Studies of mineralization of embryonic spicules and of the sea urchin genome have identified several putative mineralization-related proteins. These predicted proteins have not been isolated or confirmed in mature mineralized tissues," researchers in the United States report.

"Mature Lyte-chinus variegatus teeth were demineralized with 0.6 N HCl after prior removal of non-mineralized constituents with 4.0 M guanidinium HCl. The HCl-extracted proteins were fractionated on ceramic hydroxyapatite and separated into bound and unbound pools. Gel electrophoresis compared the protein distributions. The differentially present bands were purified and digested with ...
