# Product Name Applications Reactivity
The proliferation of NIH/3T3 cells treated with increasing concentrations of mFGF basic was assessed. After 24 hr treatment, cells were labeled with BrdU for 4 hrs. BrdU incorporation was determined by ELISA and the OD450-OD690 was determined.
The purity of recombinant mFGF basic was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant mFGF basic and staining overnight with Coomassie Blue.
Western blot analysis of extracts from NIH/3T3 cells, untreated or treated with mFGF basic for 10 min, using Phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) (D13.14.4E) XP® Rabbit mAb #4370 (upper) and p44/42 MAPK (Erk1/2) (137F5) Rabbit mAb #4695 (lower).

Storage

Stable in lyophilized state at -20°C for 1 year after receipt. Sterile stock solutions reconstituted with carrier protein are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles.
Maintain sterility. Storage at -20°C should be in a manual defrost freezer.

Product Description

MW (kDa) 17
Purity >98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mFGF basic. All lots are greater than 98% pure.
Endotoxin Less than 0.01 ng endotoxin/1 μg mFGF basic.
Activity The bioactivity of recombinant mFGF basic was determined in a NIH/3T3 cell proliferation assay. The ED50 of each lot is between 50-400 ng/ml.
Molecular Formula Recombinant mFGF basic does not have a Met on the amino terminus and has a calculated MW of 16,354. DTT-reduced and non-reduced protein migrate as 17 kDa polypeptides. The expected amino terminal ALPED of recombinant mFGF basic was verified by amino acid sequencing.

Source / Purification

Recombinant mouse FGF basic (mFGF basic) Ala11-Ser154 (Accession #NP_032032) was produced in E. coli at Cell Signaling Technology.

Background

FGF basic (FGF2) is producted in both embryonic and adult cell types, and contributes to the pathogenesis of various diseases, including cancer and atherosclerosis (1). FGF basic is involved in developmental processes and regulates differentiation, proliferation, and migration (1-6). FGF basic is a critical factor for growing embryonic stem cells in culture without inducing differentiation. FGF basic has a high affinity for heparan sulfate (1,2) and binding is a step in the FGF basic activation of FGFR tyrosine kinase. There are four distinct FGF receptors and each has multiple splice variants. FGF basic binds with high affinity to many, but not all, FGFRs. Signaling cascades activated through FGF basic binding to FGFR include the ras-raf-MAPK, PLCγ/PKC, and PI3K/AKT pathways (1).
