Recombinant Human FGF basic/FGF2/bFGF, 145 aa TC Grade, CF Summary

Product Specifications

Endotoxin Level
<0.01 EU per 1 μg of the protein by the LAL method.
Activity
The protein is used at 20 ng/mL to support a 100-fold expansion of rat cortical neural stem cells or mouse cortical stem cells over 3 passages. Cells were cultured in N2 plus medium and supplemented with FGF basic every day. Measured in a cell proliferation assay using NR6R‑3T3 mouse fibroblast cells. Raines, E.W. et al. (1985) Methods Enzymol. 109:749. The ED50 for this effect is 0.3-3 ng/mL.

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Scientific Data

SEC-MALS View Larger

Recombinant human FGF basic/FGF2/bFGF, 145 aa TC Grade (Catalog # 4114-TC) has a molecular weight (MW) of 17.2 kDa as analyzed by SEC-MALS, suggesting that this protein is a monomer.  MW may differ from predicted MW due to post-translational modifications (PTMs) present (i.e. Glycosylation).

Cell Culture Staining for the stage-specific markers, Oct-4A, Snail, NKX2.5, and Troponin T at select time points during cardiomyocyte differentiation of iPSCs View Larger

JOY6 human iPSCs were cultured in media containing Cultrex™ Stem Cell Qualified RGF BME (3434-010-02) and N21-MAX Insulin Free Media Supplement (AR010) along with Recombinant Human Activin A on day 0, Recombinant Human FGF-basic (Catalog # 4114-TC), Recombinant Human BMP-4, and CHIR99021 (4423) on days 1-5, and Recombinant Human Dkk-1 (5439-DK) on days 5-7 to induce cardiomyocyte differentiation. Cells were then cultured in media supplemented with N21-MAX Insulin Free Media Supplement (AR010) on days 7-12 and media supplemented with N21-MAX Media Supplement (AR008) from day 12 and beyond. Cells were fixed and stained for stage-specific markers at select time points during the procedure. The pluripotency marker Oct-4 was detected using a Mouse Anti-Human Oct-4A Monoclonal Antibody (MAB17591). The mesoderm marker, Snail is expressed intermediately during differentiation (Day 1). It was detected using a Goat Anti-Human Snail Polyclonal Antibody (AF3639). The cardiomyocyte markers NKX2.5 and Troponin T are not present in cells during early (Day 0) and intermediate (Day1) differentiation and become more highly expressed during the later stages of differentiation (Day 7, Day 30). NKX2.5 was detected using a Goat Anti-Human NKX2.5 Polyclonal Antibody (AF2444) and Troponin T was detected using a Mouse Anti-Human Cardiac Troponin T Monoclonal Antibody (MAB1874). Snail and NKX2.5 primary antibodies were visualized with a NorthernLights™ 557-conjugated Donkey Anti-Goat IgG Secondary Antibody (NL001). Oct-4 and Troponin T were visualized with a NorthernLights 557-conjugated Donkey Anti-Mouse IgG Secondary Antibody (NL007).

JOY6 human induced pluripotent stem cells (iPSCs) were differentiated into cardiomyocytes in media containing Cultrex™ Stem Cell Qualified Reduced Growth Factor Basement Membrane Extract (3434-010-02) and N21-MAX Insulin Free Media Supplement (AR010) along with Recombinant Human Activin A on day 0, Recombinant Human FGF-basic (Catalog # 4114-TC), Recombinant Human BMP-4, and CHIR99021 (4423) on days 1-5, and Recombinant Human Dkk-1 (5439-DK) on days 5-7. Following culture in media supplemented with N21-MAX Insulin Free Media Supplement (AR010) on days 7-12 and media supplemented with N21-MAX Media Supplement (AR008) from day 12 and beyond, cells were fixed and stained for the atrial-specific marker, MLC2a, and the ventricle-specific marker, MYH7 using a Rabbit Anti-Human MYH7 Monoclonal Antibody (MAB90961).

Background: FGF basic/FGF2/bFGF

FGF basic (also known as FGF2 and HBGF-2) is an 18-34 kDa, heparin-binding member of the FGF superfamily of molecules (1-3). Superfamily members are characterized by the presence of a centrally placed beta -trefoil structure. FGF acidic (FGF1) and FGF basic (FGF2) were the first two identified FGFs, and the designations acidic and basic refer to their relative isoelectric points. Human FGF basic is 288 amino acids (aa) in length. There are multiple start sites, four of which utilize atypical CUG codons, and one that initiates at an AUG start site (4-6). The four CUG start sites generate high molecular weight (HMW) FGF basic. There is a 34 kDa, 288 aa form, a 24 kDa, 210 aa form, a 22.5 kDa, 201 aa form, and a 22 kDa, 196 aa form. All are retained intracellularly, undergo extensive methylation, and possess one or more nuclear localization signals (NLS) (7-9). The AUG initiating form is 18 kDa and 155 aa in length. There is no signal sequence (ss). It is, however, secreted directly through the plasma membrane via a mechanism that appears to be dependent upon tertiary structure (10). In place of a ss, there is purportedly a 9 aa N-terminal prosegment that precedes a 146 aa mature segment (11). Early isolations of 18 kDa bovine FGF basic yielded 146 aa molecules, an effect attributed to the presence of acid proteases (12). The molecule contains a heparin-binding site (aa residues 128-144), and undergoes phosphorylation at Ser117 (13). There is also an ill-defined C-terminal NLS that may be more “functional” (or 3-dimensional) than structural (7). Human 146 aa FGF basic is 97% aa identical to mouse FGF basic (14).
