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

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).

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 (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).

FAQs for FGF basic/FGF2/bFGF (4114-TC). (Showing 1 - 1 of 1 FAQs).

1. I am looking for an ovine antibody for bFGF and PDGF-AB and ELISA Kits for both. It is for a research work on meniscus healing in sheep. Do you have anything suitable? How is the homology with sheep? Is it ever tested and/or published in papers?
   • Unfortunately, most of the products you are interested in have not yet been tested in sheep, but this should not be a problem, due to sequence homology, and our Innovators Reward Program. In terms of an antibody for bFGF, also called FGF-2, we have several antibodies that are validated to detect the bovine protein, which is almost identical to that from sheep (99% homology). We only have FGF2 ELISA kits that have been tested with human or mouse. Mouse FGF-2 has 94% homology with sheep; human has 98% homology for most of its sequence, but also has an additional stretch of amino acids that is not present in the sheep protein. I therefore think that the mouse kit would be most suitable, just in case the human kit targets the region of the human protein not present in mouse. We sell antibodies to PDGF-A or PDGF-B rather than PDGF-AB. We don't have any PDGF-A antibodies that have been tested in sheep but there are several options you may find of interest. There isn't a sheep PDGFA sequence in UniProt, so I can't comment on how similar it is to the PDGFA from other species. Nevertheless, our NBP1-52533 PDGFB antibody has been shown to work in sheep. We sell two PDGF-AB ELISA kits , but these are for human and rat. I'm not sure how well these would work with sheep. Note that if you test a product with a species (or application) that it has not yet been validated in, you are eligible for our Innovator's Reward: Novus would provide you a 50% refund on the purchased product as well as a 50% discount on a future product of equal or lesser value. You would email innovators@novusbio.com to apply for your award, and we
