Product Specs

Introduction
Growth Differentiation Factor-7 (GDF-7), a member of the Bone Morphogenetic Protein (BMP) family within the Transforming Growth Factor-beta (TGF-β) superfamily, exerts its biological effects by binding to a heterodimeric receptor complex. This complex consists of a type 1 receptor (BMPR-IB) and a type II receptor (BMPR-II or Activin RII), both of which are serine/threonine kinase receptors. Upon ligand binding, GDF-7 signaling activates Smad proteins through phosphorylation. GDF-7 plays a crucial role in tendon and ligament formation and repair. Additionally, it regulates bone formation, mesenchymal stem cell differentiation, neuronal differentiation, and axon guidance.
Description
Recombinant Mouse GDF7, expressed in E. coli, is a non-glycosylated homodimeric protein. Each GDF7 molecule comprises two polypeptide chains, each containing 146 amino acids. The molecular weight of the dimer is 29.8 kDa. GDF-7 undergoes purification using proprietary chromatographic techniques.
Physical Appearance
Sterile, white powder obtained by lyophilization (freeze-drying).
Formulation
GDF7 protein was subjected to lyophilization from a 0.2 µm filtered solution concentrated in 30% Acetonitrile and 0.1% Trifluoroacetic acid (TFA).
Solubility
To reconstitute the lyophilized GDF-7, it is recommended to dissolve it in sterile 18 MΩ·cm H2O at a concentration of at least 100 µg/ml. The reconstituted solution can be further diluted in other aqueous solutions.
Stability
Lyophilized GDF7 remains stable at room temperature for up to 3 weeks; however, it is advisable to store it desiccated at a temperature below -18°C. Once reconstituted, GDF-7 should be stored at 4°C for 2-7 days. For long-term storage, freezing at -18°C is recommended. To enhance stability during storage, the addition of a carrier protein (0.1% Human Serum Albumin (HSA) or Bovine Serum Albumin (BSA)) is recommended. Repeated freeze-thaw cycles should be avoided.
Purity
The purity of GDF7 is determined to be greater than 95.0% using the following methods:
(a) Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) analysis.
(b) Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) analysis.
Biological Activity
The ED50, defined as the concentration required to induce half-maximal alkaline phosphatase production in murine ATDC5 cells, is determined to be less than 0.5 µg/ml. This corresponds to a specific activity greater than 2000 International Units (IU) per mg.
Synonyms
Growth/differentiation factor 7, GDF-7, Gdf7.

Product Science Overview

Background and Discovery

GDF-7 was first identified as a protein involved in the development and differentiation of various tissues. It is synthesized as a large precursor protein that consists of an N-terminal signal sequence, a pro-region, and a C-terminal mature peptide . The mature peptide is responsible for the biological activity of GDF-7.

Biological Functions

GDF-7 plays a crucial role in the development and repair of tissues. It is particularly important in the differentiation of tendon and ligament cells, as well as in the repair of injured organs . GDF-7 has been shown to promote the expansion of hepatic progenitor cells in liver fibrosis, suggesting a potential pro-regenerative function .

Mode of Action

GDF-7 exerts its effects by binding to specific receptors on the surface of target cells. These receptors are part of the BMP receptor family, which includes BMPR1A and BMPR2 . Upon binding to these receptors, GDF-7 activates intracellular signaling pathways that lead to the expression of genes involved in cell growth, differentiation, and repair.

Recombinant Mouse GDF-7

Recombinant Mouse GDF-7 is produced using E. coli expression systems. The recombinant protein is purified to high levels of purity and is available in both carrier-free and carrier-containing formulations . The carrier protein, typically Bovine Serum Albumin (BSA), enhances protein stability and shelf-life .

Applications

Recombinant Mouse GDF-7 is used in various research applications, including:

  • Cell and tissue culture: To study the effects of GDF-7 on cell differentiation and tissue repair.
  • ELISA standards: As a standard in enzyme-linked immunosorbent assays (ELISAs) to quantify GDF-7 levels in biological samples.
  • In vitro studies: To investigate the signaling pathways activated by GDF-7 and its role in tissue development and repair .
Storage and Stability

Recombinant Mouse GDF-7 is typically stored at -20 to -70°C to maintain its stability. It is important to avoid repeated freeze-thaw cycles to prevent degradation of the protein .
