Recombinant Human Bone Morphogenetic
Protein -2 (BMP2)
(Cat. No.: C012)
Background:
Belongs to the Bone-growth regulatory
factors that are members of the
transforming growth factor-beta (TGF-beta)
superfamily of proteins. They are
synthesized as large precursor molecules
which are cleaved by proteolytic
enzymes. The active form can consist of
a dimer of two identical proteins or a
heterodimer of two related bone
morphogenetic proteins.
Description:
Recombinant Human Bone Morphogenetic
protein-2 produced in E. coli is a
homodimeric, non-glycosylated,
Polypeptide chain containing 115 amino
acids and having a molecular mass of
26018 Dalton.
BMP2
is purified by proprietary
chromatographic techniques.
Quality Control:
Biological activity:
BMP-2 is fully biologically active when
compared to standard. The ED50 as
determined by the cytolysis of MC3T3-E1
cells is less then 50 ng/ml.
Purity:
Greater than 95% as determined by
(a) Analysis by SEC-HPLC.
(b) Analysis by reducing and
non-reducing SDS-PAGE Silver Stained
gel.
Amino-Acid Sequence:
The sequence of the first five
N-terminal amino acids was determined
and was found to be Met-Gln-Ala-Lys-His.
Endotoxin:
Less than 0.1 ng/µg (IEU/µg) of Bone
Morphogenetic protein-2.
Formulation:
BMP2 was lyophilized from a concentrated
(1mg/ml) sterile solution containing
10mM sodium citrate pH=3.5.
Storage:
Lyophilized BMP2 although stable at room
temperature for 3 weeks, should be
stored desiccated below -18oC.
Upon reconstitution BMP2 should be
stored at 4oC between 2-7
days and for future use below -18oC.
For long term storage it is recommended
to add a carrier protein (0.1% HSA or
BSA).
Please avoid freeze-thaw cycles
Reconstitution:
It is recommended to reconstitute the
lyophilized rHuBMP2 in sterile 20mM HAc
(acetic acid) not less than 100µg/ml,
which can then be further diluted to
other aqueous solutions. |
