Basic fibroblast growth factor is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The HPR -binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors.

The protein was lyophilized from a concentrated (1mg/ml) solution in 20mM Tris-HCl, pH7.4 and 1M NaCl.

Greater than 98.0% as determined by Analysis by SDS-PAGE.

The ED₅₀, calculated by the dose-dependant proliferation of murine balb/c 3T3 cells is <0.1ng/ml, corresponding to a specific activity of graeter than 1.0x10⁷ Units/mg.

FGF 2 HUMAN: Insights into Fibroblast Growth Factor-2

Basic Fibroblast Growth Factor or FGF 2 HUMAN is a protein with crucial roles in cell growth, tissue repair, and embryonic development. This is part of the larger fibroblast growth factor family and is vital for various biological processes, including the modulation of cell survival activities.

Production and Properties

Produced in E. coli, FGF 2 is a non-glycosylated polypeptide chain possessing 154 amino acids with a molecular weight of about 17.2 kDa. It is purified through advanced chromatographic techniques, ensuring high purity and activity for laboratory use.

Physical Characteristics and Preparation

The physical form of FGF 2 HUMAN is a sterile, white lyophilized powder. For experimental use, it is reconstituted with sterile water to at least 100µg/ml. This reconstitution is crucial for maintaining the integrity and effectiveness of the protein in various research applications.

Storage and Handling

To maintain stability, lyophilized FGF 2 should be stored at -18°C and used within three weeks if kept at room temperature. Once reconstituted, it should be kept at 4°C and used within 2-7 days or stored at -18°C for longer-term storage.

Proper handling and avoiding repeated freeze-thaw cycles are essential to preserve the protein's functionality.

Purity and Biological Activity

FGF 2 is characterized by a purity greater than 98%, verified by SDS-PAGE analysis. Its biological activity is primarily defined by its efficacy in promoting the proliferation of specific cell lines, with an effective dose (ED50) typically below 0.1 ng/ml.

Research Applications and Impact

In the research context, FGF 2 is used extensively to study its effects on cell migration, proliferation, and angiogenesis. Moreover, its role in disease models, particularly in cancer and tissue repair studies, makes it a valuable resource for developing new therapeutic approaches.

Usage Guidelines

FGF 2 HUMAN is strictly for laboratory research use and is not suitable for drug development, food production, or cosmetic applications. Researchers are advised to comply with safety and handling guidelines to ensure that experiments are conducted under optimal conditions.

The Broad Impact on Development and Disease

FGF-2 is known for its multifunctional role across numerous biological processes such as tissue repair, embryonic development, angiogenesis, and even tumorigenesis.

This growth factor, existing in various synonymous forms such as Basic FGF, FGF-b, and HBGF-2, is essential in cellular processes that underpin both health and disease.

Furthermore, FGF-2's ability to bind to cellular receptors triggers a cascade of signaling pathways, including PI3K/Akt, MAPK/ERK, and PLCγ, which in turn influence cell growth, migration, and survival.

These pathways are pivotal in mediating the factor's diverse effects on cell behavior, contributing to its critical roles in wound healing, angiogenesis, and tissue remodeling.
