Introduction
Growth differentiation factor 10 (GDF10), a member of the bone morphogenetic protein (BMP) family within the transforming growth factor-beta (TGF-β) superfamily, plays a crucial role in skeletal development. Expressed in various tissues including the femur, brain, lung, skeletal muscle, pancreas, and testis, GDF10 contributes to head formation and potentially multiple aspects of skeletal morphogenesis. Human GDF10 mRNA is detected in the fetal cochlea and lung, as well as in adult tissues such as the testis, retina, pineal gland, and other neural tissues. GDF10, like other BMP family members, regulates cell growth and differentiation in both embryonic and adult tissues. These proteins share a characteristic polybasic proteolytic processing site, which upon cleavage, yields a mature protein containing seven conserved cysteine residues.
Description
Recombinant human GDF10, produced in E. coli, is a single, non-glycosylated polypeptide chain comprising 111 amino acids (residues 369-478). With a molecular mass of 12.5 kDa, it encompasses the bioactive region of GDF10. The protein is purified using proprietary chromatographic techniques to ensure high purity.
Physical Appearance
Clear, colorless solution, sterile-filtered.
Formulation
The GDF10 solution is provided at a concentration of 1 mg/ml in a buffer containing 10 mM sodium citrate (pH 3.5), 1 mM dithiothreitol (DTT), 40% glycerol, and 0.1 M sodium chloride.
Stability
For short-term storage (up to 2-4 weeks), the GDF10 solution can be stored at 4°C. For extended storage, it is recommended to store the protein frozen at -20°C. To further enhance long-term stability, the addition of a carrier protein such as 0.1% human serum albumin (HSA) or bovine serum albumin (BSA) is advised. Repeated freeze-thaw cycles should be avoided to maintain protein integrity.
Purity
The purity of GDF10 is determined to be greater than 95% by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis.
