Background
Human FGF-2 (bFGF), encoded by the FGF2 gene, is a member of the fibroblast growth factor (FGF) family. Fibroblast growth factor was found in pituitary extracts in 1973 and then tested in a bioassay that caused fibroblasts to proliferate. After further fractionating the extract using acidic and basic pH, two different forms have isolated that named "acidic fibroblast growth factor" (FGF-1) and "basic fibroblast growth factor" (FGF-2). Human FGF-2 (bFGF) shares 54 % amino acid sequence identity with aFGF. Affinity between FGF-2 (bFGF) and its receptors can be increased by heparin or heparan sulfate proteoglycan. FGF-2 (bFGF) plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. FGF-2 (bFGF) are also involved in a variety of biological processes, including embryonic development , morphogenesis, tissue repair, tumor growth and invasion. Additionally, FGF-2 (bFGF) is frequently used for a critical component of cell culture medium, e.g., human embryonic stem cell culture medium, serum-free culture systems.

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? ..show answer..
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.
