タンパク質構築情報
A DNA sequence encoding the mature form of mouse MSTN (NP_034964.1) (Asp 268-Ser 376) was fused with the Fc region of human IgG1 at the N-terminus.
分子量
The recombinant mouse MSTN/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 369 amino acids and has a predicted molecular mass of 40.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmMSTN/Fc monomer is approximately 45 kDa.

Mouse GDF-8 HEK293 Overexpression Lysate: 用法

調製方法
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.
溶解バッファー
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
おすすめの用法
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.
バッファー
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.
アプリケーション
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

GDF-8 背景情報

GDF-8 / Myostatin / MSTN is a member of the bone morphogenetic protein (BMP) family and the TGF-beta superfamily. This group of proteins is characterized by a polybasic proteolytic processing site which is cleaved to produce a mature protein containing seven conserved cysteine residues. The members of this family are regulators of cell growth and differentiation in both embryonic and adult tissues. GDF-8 / Myostatin / MSTN is highly expressed in skeletal muscle, and myostatin loss-of-function leads to doubling of skeletal muscle mass. Experiments in mice have improved that GDF-8 / Myostatin / MSTN is a key regulator of mesenchymal stem cell proliferation and differentiation, and mice lacking Myostatin encoding gene show decreased body fat and a generalized increase in bone density and strength. The increase in bone density is observed in most anatomical regions, including the limbs, spine, and jaw, and myostatin inhibitors have been observed to significantly increase bone formation. GDF-8 / Myostatin / MSTN is also expressed in the early phases of fracture healing, and GDF-8 / Myostatin / MSTN deficiency leads to increased fracture callus size and strength. Together, these data suggest that GDF-8 / Myostatin / MSTN has direct effects on the proliferation and differentiation of osteoprogenitor cells, and that GDF-8/Myostatin/MSTN antagonists and inhibitors are likely to enhance both muscle mass and bone strength.
