This Human BMP-2 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of BMP-2 protein (Cat: 10426-H01H) from the overexpression lysate was verified.
A DNA sequence encoding the mature form of human BMP2 (NP_001191.1) (Gln 283-Arg 396) was fused with the Fc region of human IgG1 at the C-terminus. The mature form sequences of human, mouse, rat, rhesus and canine BMP2 are identical.
The recombinant human Fc/BMP2 is a disulfide-linked homodimeric protein. The reduced monomer consists of 351 amino acids and has a predicted molecular mass of 39.5 kDa. As a result of glycosylation, the apparent molecular mass of rhFc/BMP2 monomer is approximately 45 kDa in SDS-PAGE under reducing conditions.
Human BMP-2 HEK293 Overexpression Lysate: 用法
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.
2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
安定性 & 保存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB) Optimal dilutions/concentrations should be determined by the end user.

BMP-2 protein, like other bone morphogenetic proteins, plays an important role in the development of bone and cartilage. BMP-2 protein is involved in the hedgehog pathway, TGF beta signaling pathway, and cytokine-cytokine receptor interaction. BMP-2 and BMP-7 are osteogenic BMPs that have been demonstrated to potently induce osteoblast differentiation in a variety of cell types. BMP-2, BMP-4 and BMP-7 are known to be of major importance in bone formation and repair. In cancerous tissues BMP-2 protein may play an important role in the progression of glioma.
