产物英文概述
Bone Morphogenetic Protein 2 is one of the BMPs, some of which belong to the TGF-beta superfamily (BMP2-7). There are more than thirteen BMPs have been discovered nowadays and they are involved in inducing cartilage and bone formation. BMP-2 is expressed in a variety of tissues including lung, spleen, brain, liver, prostate ovary and small intestine. It is a potent osteoinductive cytokine and plays its role in association with osteoconductive carriers such as collagen and synthetic hydroxyapatite. As it shown to stimulate the production of bone, the recombinant human BMP-2 is available for orthopaedic usage and dentisty. The functional form of BMP-2 is a disulflde-linked homodimer and about 26 kDa The precursor of BMP-2 is 259 a.a., containing the 23 a.a. N-terminal signal sequence which will be cleaved by a furin-type protease to form the mature peptide.来历
Escherichia coli.份子量
Approximately 26.0 kDa, a homodimeric protein consisting of two 115 amino acid non-glycosylated polypeptide chains.生物活性
Fully biologically active when compared to standard. The ED50 as determined by inducing alkaline phosphatase production of murine ATDC5 cells is less than 200 ng/ml, corresponding to a specific activity of > 5.0 × 103 IU/mg.表面
Sterile filtered white lyophilized (freeze-dried) powder.配方
Lyophilized from a 0.2 um filtered concentrated solution containing 10 mM sodium citrate pH 3.5.内毒素
Less than 1 EU/ug of rHuBMP-2 as determined by LAL method.消融申明
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled H2O to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. Do not reconstitute in PBS or cell culture media.贮存前提
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.参考材料
