NS0-Derived Recombinant Human BMP-4 (Accession # P12644)
<0.1 EU/µg as determined by the LAL method
This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.3 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.
Storage and Handling
The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 2-8 µg/ml.
Western Blotting: To detect Human BMP-4 this monoclonal antibody can be used at a concentration of 1-2 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:M114 and a chromogenic substrate such as PN:T343. The detection limit for Human BMP-4 is 25 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Mouse Anti-Human Bone Morphogenic Protein 4 (BMP-4) (Clone 66110) recognizes an epitope on Human BMP-4. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
Bone morphogenetic protein 4 (BMP4) belongs to the TGF-β superfamily of proteins. Like other bone morphogenetic proteins, it is involved in bone and cartilage development. It is mainly involved in tooth and limb development, fracture repair, muscle development, bone mineralization, and uteric bud development. BMP4 has also been implicated in Fibrodysplasia Ossificans Progressiva in which it is underexpressed. In human embryonic development, BMP4 is a critical signaling molecule required for the early differentiation of the embryo and establishing of a dorsal-ventral axis. BMP4 is secreted from the dorsal portion of the notochord, and it acts in concert with sonic hedgehog (released from the ventral portion of the notochord) to establish a dorsal-ventral axis for the differentiation of later structures. BMP4 stimulates differentiation of overlying ectodermal tissue. Inhibition of the BMP4 signal (by chordin, noggin, or follistatin) causes the ectoderm to differentiate into the neural plate. If these cells also receive signals from FGF, they will differentiate into the spinal cord; in the absence of FGF the cells become brain tissue. Recombinant human BMP-4, expressed in HeLa cells, is a 31-36 kDa homodimeric glycoprotein. BMP-4 and BMP-7 are each 98% conserved between human and mouse. Human BMP-4 shares 85% aa sequence identity with human BMP-2 and less than 50% aa sequence identity with other BMPs. Human BMP-7 shares approximately 60 - 70% aa sequence identity with BMP-5, -6, and -8 and less than 50% aa sequence identity with other BMPs.
