1999554-1	1991	Bone morphogenetic protein (BMP) was extracted from human dentin matrix with 4 mol/L guanidine-HCl and was purified by liquid chromatography.	Guanidine	85-98	bone morphogenetic protein 1	Homo sapiens	0-26	
1999554-1	1991	Bone morphogenetic protein (BMP) was extracted from human dentin matrix with 4 mol/L guanidine-HCl and was purified by liquid chromatography.	Guanidine	85-98	bone morphogenetic protein 1	Homo sapiens	28-31	
1999554-2	1991	SDS-PAGE and IEF showed that the purified BMP was homogeneous and induced new bone formation in situ after three weeks when implanted into muscle pouches in Wistar rats.	Sodium Dodecyl Sulfate	0-3	bone morphogenetic protein 1	Homo sapiens	42-45	
1999554-3	1991	The molecular weight of BMP was estimated to be about 20.0 kDa by SDS-PAGE, and the pI value was 8.8 by IEF.	Sodium Dodecyl Sulfate	66-69	bone morphogenetic protein 1	Homo sapiens	24-27
