Background

FGF basic (also known as FGF-2 and HBGF-2) is a member of the FGF superfamily of mitogenic proteins which show 35-60% amino acid conservation. FGF acidic and basic are unique from other members of the family in that they lack classical secretory signal peptides. However, they are both readily secreted from cells by an alternative secretory pathway involving direct translocation and aided by several chaperones. FGF acidic (FGF-1) and FGF basic (FGF-2) were the first two identified FGFs, and the designations acidic and basic refer to their relative isoelectric points. The full length human FGF basic protein is 288 amino acids, but there are multiple start sites which produce various shorter forms. Further adding to the complexity, a variety of forms of FGF basic are produced as a result of N-terminal extensions. These extensions affect localization of FGF basic in cellular compartments but do not affect biological activity. FGF basic has been isolated from a number of sources, including neural tissue, adrenal cortex, pituitary gland, corpus luteum, and placenta. Binding of FGF to heparin or cell surface heparan sulfate proteoglycans is required for FGF binding with high affinity to FGF receptors. FGF basic stimulates proliferation of all cells of mesodermal origin as well as many cells of neuroectodermal, ectodermal, and endodermal origin. FGF basic also induces neuronal differentiation, survival, and regeneration, and modulates embryonic development and differentiation. These observed in vitro functions suggest FGF basic may play a role in vivo in the modulation of such normal processes as angiogenesis, wound healing and tissue repair, embryonic development and differentiation, and neuronal function and neural degeneration. Additionally, FGF basic may also participate in the development of several pathological conditions resulting from excessive cell proliferation and/or angiogenesis.

FAQs for FGF basic/FGF2/bFGF (233-FB). (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 two antibodies that are validated to detect the bovine protein, which is almost identical to that from sheep (99% homology). Here is a link to those FGF-2 antibodies. 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.
