Background
PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.
PDGF BB HUMAN: Overview of Its Production, Properties, and Clinical Significance PDGF BB HUMAN, standing for Platelet-Derived Growth Factor BB, is a powerful protein in the field of medical research, particularly in cell growth and healing. This growth factor plays a crucial role in the development and repair of tissues by stimulating cells primarily of mesenchymal origin. Characteristics and Production PDGF is produced as a recombinant protein in E. coli. It presents as a homodimer consisting of two identical polypeptide chains, each containing 109 amino acids, culminating in a total molecular mass of 24.3 kDa. The production process ensures a high-purity product, which is essential for reliable scientific results. Physical Properties and Formulation This growth factor appears as a white, sterile, lyophilized powder. It is formulated in a buffered solution (PBS, pH 7.4) and then filtered to ensure sterility and purity, essential for laboratory use. The formulation process is designed to maintain the stability and activity of the protein under various research conditions. Solubility and Storage Instructions PDGF BB is recommended to be reconstituted in sterile water to achieve a concentration of no less than 100µg/ml. This solution can then be diluted further to meet experimental needs. Once reconstituted, the protein should be stored at 4°C for short-term use (2-7 days) and below -18°C for long-term storage. Avoiding freeze-thaw cycles is crucial to preserve its biological activities. Stability and Purity The lyophilized form of PDGF BB remains stable at room temperature for up to three weeks but requires desiccation for longer storage. Moreover, the purity of this growth factor exceeds 95%, as confirmed by rigorous testing, including RP-HPLC and SDS-PAGE, ensuring that researchers receive a highly effective product. Research Applications PDGF BB HUMAN is widely used in laboratory research to explore various biological processes, including wound healing, angiogenesis, and the development of certain types of cancers. It is also instrumental in studying the cellular mechanisms underlying tissue repair and regeneration. Biological Activity The effectiveness of PDGF BB is measured by its ability to stimulate the proliferation of Balb/c 3T3 cells, with an effective dose (ED50) ranging from 1.0 to 3.0 ng/ml. This high level of activity underscores its utility in promoting cell growth, making it an invaluable tool in tissue engineering and regenerative medicine. Usage Guidelines It is important to note that PDGF BB HUMAN is intended solely for laboratory research and is not suitable for drug, food, or cosmetic applications. Researchers must handle this growth factor under controlled conditions to ensure safety and efficacy. Essentially, PDGF BB is a pivotal component in the toolkit of biomedical researchers, offering profound insights into cellular processes and potential therapeutic approaches. Also, its well-defined properties and controlled production make it a staple in studies focused on cell growth and tissue repair.
