FGF-2 Protein, Rat is a growth factor and signaling protein encoded by the FGF2 gene.


Recombinant Rat Basic Fibroblast Growth Factor is a potent mitogen and chemoattractant for endothelial cells as well as fibroblasts. Basic fibroblast growth factor (bFGF) is a heparin-binding mitogen for mesoderm-derived cells, also acts as a mitogen, differentiation inducing and maintenance factor for many neuroectodermal cells including glial cells, neurons, paraneurons, and their tumor counterparts. The molecule is expressed in several types of neuroectodermal cells. bFGF occurs in many neuronal target tissues, and can prevent ontogenetic as well as lesion-induced neuron death[1]. In vitro, basic fibroblast growth factor induces an angiogenic phenotype in endothelial cells, which includes chemotaxis, mitogenesis, protease production, beta-integrin expression, and tube formation in three-dimensional gels. It acts by binding to specific tyrosine kinase receptors and to cell-associated heparan sulfate proteoglycans[2].

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Active Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
