Stock solutions can also be prepared at 50-100 μg/mL in sterile buffer (PBS, HPBS, DPBS, or EBSS) containing carrier protein such as 0.2-1 % BSA or HSA and stored in working aliquots at -20 °C to -70 °C.

Buffer: 0.22 μm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2, 1 mM DTT.

Preservative: Dithiothreitol (DTT)

Precaution of Use: This product contains Dithiothreitol (DTT): a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

Handling Advice: Avoid repeated freeze/thaw cycles.

Storage: -20 °C

Storage Comment: Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year.

Target Details

Target: FGF2 (Fibroblast Growth Factor 2 (Basic) (FGF2))

Alternative Name: FGF-Basic

Background: FGFb is a member of the fibroblast growth factor (FGF) family which includes 23 members. FGFb is expressed in almost all tissues and play important roles in a variety of normal and pathological processes, including development, wound healing and neoplastic transformation. FGFb is mitogenic for many cell types, both epithelial and mesenchymal. FGFb shows potent angiogenic activity and has been implicated in tumor angiogenesis (2). In prostate, bladder, and renal cancers, FGFb regulates the induction of metalloproteinases (MMP) that degrade extracellular matrix proteins, thus facilitating tumor metastasis (3). FGFb binds to a family of four distinct, high affinity tyrosine kinase receptors, designated FGFR-1 to -4 (4). In addition, FGFb binds to the ECM, and heparan sulfate (HS) is an essential and dynamic regulator of fibroblast growth factor (FGF) signaling. Two fundamentally different crystallographic models have been proposed to explain, at the molecular level, how HS/heparin enables FGF and FGF receptor (FGFR) to assemble into a functional dimer on the cell surface (5), although there is controversy regarding the exact manner by which this occurs.

Molecular Weight: The 145 amino acid recombinant protein has a predicted molecular mass of 16,310 Da. The DTT-reduced and non-reduced protein migrate at approximately 18kDa by SDS-PAGE. This protein may or may not contain an N-terminal methionine.
