产品特性
Recombinant human BMP11 / GDF11 protein expressed in E. coli.
Produced with end-sequenced ORF clone
Tested for bioactivity.
纯度
> 95 % as determined by SDS-PAGE and Coomassie blue staining
内毒素水平
Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).
Biological Activity Comment
ED50 was determined by its ability to inhibit induced alkaline phosphatase production by ATDC-5 chondrogenic cells. The expected ED50 for this effect is 0.08-0.10 ug/ml.
Recombinant human proteins can be used for: Native antigens for optimized antibody production Positive controls in ELISA and other antibody assays Protein-protein interaction In vitro biochemical assays and cell-based functional assays

注意事项
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1~1.0 mg/mL, and keep pH at acidic condition below 5.0 Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (e.g. 0.1 % BSA) and store in working aliquots at -20 °C to -80 °C

-80 °C
储存方法
Store at -80°C. Thaw on ice, aliquot to individual single-use tubes, and then re-freeze immediately. Only 2-3 freeze thaw cycles are recommended.
This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein plays a role in the development of the nervous and other organ systems, and may regulate aging.
