The matricellular protein osteopontin binds to cell surface receptors and is secreted into many body fluids including milk, blood and urine, depending on the organ of origin. This makes osteopontin an ideal candidate for being a biomarker as the secreted form is easily obtained in throwaway fluids, and mimics the cellular environment from which it is released. Osteopontin is important in immune responses and inflammation as well as bone generation and remodeling. In autistic children, serum levels of osteopontin are correlated to the severity of disease, probably due to a brain inflammation pattern in these children. In aortic valve sclerosis and stenosis, increased levels of secreted osteopontin are also noted. Osteopontin has also been suggested as a cancer biomarker, since it is associated with tumor formation, progression and metastasis. In bone and tooth formation osteopontin is known to be a negative regulator of parathyroid hormone-related protein receptor, which induces osteogenesis. Without appropriate levels of osteopontin, bone growth continues unregulated, and leads to specific bone cancers. In short, osteopontin is a strong marker for bone growth, inflammation and certain cancers.

FAQs for Osteopontin/OPN Antibody (NB110-89062). (Showing 1 - 1 of 1 FAQs).

  1. I am very interested in your anti-human osteopontin (SPP1) (cat #NB110-89062). I work with bovine and would like to use the antibody in the blot. According to your description, the immunogen is a synthetic peptide which binds to the C-terminus of the human. The sequences of the C-termini are very similar in humans and cattle. Could you kindly tell me what amino acids against the C-terminus of the human antibody is directed exactly?
    • The immunogen sequence for NB110-89062 lies within amino acids 284-314 of isoform A, UniProt P10451. I have carried out a UniProt Blast analysis of the exact immunogen sequence versus Bos taurus (bovine) proteins for you, and the result was a 95% match for both osteopontin and osteopontin-K. This is a high percentage strongly suggesting that the antibody will be suitable for bovine, although we cannot guarantee it as this has not been tested in the lab. Because you would be using NB110-89062 with a species not stated on the web page / datasheet for this product, you would not be covered by the Novus Guarantee but you would be eligible for our special Innovator's Reward program, where as a thank you for sharing your results with us (whether the antibody proved suitable or not) by completing a review, we would give you a voucher code for the price of the product.
