  • Patent number: 4627982
    Abstract: A partially purified proteinaceous bone-inducing factor of 10,000 to 30,000 daltons is described. It is derived from demineralized bovine bone by extraction with a chaotropic agent, gel filtration, cation exchange chromatography using carboxymethyl cellulose at pH 4.8 and gradient elution with NaCl at 10 mM to about 150 mM.

  • Patent number: 4434094
    Abstract: A process for partially purifying an osteogenic factor from demineralized bone particles in which nonfibrous proteins are extracted from the demineralized bone with a dissociative extractant for nonfibrous proteins, such as urea or guanidine hydrochloride, the extracted nonfibrous proteins are fractionated by anion exchange chromatography using DEAE cellulose at pH 7, the fraction not adsorbed by the DEAE cellulose is further fractionated by cation exchange chromatography using CM cellulose at pH 4.8, the fraction adsorbed by the CM cellulose is eluted therefrom and the partially purified osteogenic factor is recovered from the eluate as a .ltoreq.30,000 dalton protein isolate.
