Purification and characterization of a unique osteoinductive factor from bovine bone.
A unique protein that promotes ectopic osteoinduction in the rat has been isolated and characterized. Osteoinductive factor (OIF) was extracted from the organic matrix of bovine bone with 4 M guanidine HCl and purified by gel filtration, ion-exchange chromatography, affinity chromatography, and reversed phase high performance liquid chromatography. OIF is a glycoprotein with an apparent molecul...
متن کاملAmino acid sequence of bovine osteoinductive factor.
The complete amino acid sequence of bovine osteoinductive factor (OIF) was determined by automated Edman degradation of S-pyridylethylated bovine OIF and selected fragments. Cleavage with endoproteinase Lys-C, endoproteinase Glu-C, or endoproteinase Asp-N established all fragments in an unambiguous sequence. Bovine OIF contains 105 residues with a calculated molecular weight of 12,055. It is a ...
متن کاملRabbit bone marrow response to bovine osteoinductive proteins and anorganic bovine bone.
The effects caused by the implantation of bioabsorbable hydroxyapatite (HA) bound to a pool of bone morphogenetic proteins (BMPs) and other bone noncollagenous hydrophobic proteins mixed with anorganic bovine bone inside rabbit bone marrow were assessed. Within the interior of hollow cylindric titanium prototypes, the following biomaterials were inserted: (1) test group: HA containing a pool of...
متن کاملPurification of Factor VII from Bovine Plasma
Factor VII has been purified up to 330,000-fold from bovine plasma by adsorption on, and elution from, barium sulfate, anion exchange chromatography, gel filtration, and affinity chromatography on benzamidine coupled to Sepharose. The purified material is inhibited by diisopropylphosphorofluoridate both in its native state and after the formation of a complex with tissue factor in the presence ...
متن کاملPartial Purification and Characterization of Anticoagulant Factor from the Snake (Echis carinatus) Venom
Objective(s): Snake venoms contain complex mixture of proteins with biological activities. Some of these proteins affect blood coagulation and platelet function in different ways. Snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. In the present study, purification of anticoagulation facto...
