Polyclonal Rabbit Affinity Purified B
Sprouty is a suppressor of EGF and FGF signaling that appears to have a universal inhibitory role on tyrosine kinase signaling. Evidence suggests that it does this by binding adapter proteins and GAP, thus inactivating Ras. Sprouty expression is induced by the same pathways that it down-regulates, suggesting it plays a role in an auto-feedback loop. Sprouty was originally identified as an inhibitor of Drosophila epidermal growth factor (EGF) and fibroblast growth factor (FGF) receptor signaling during tracheal development. Four isoforms of mammalian sprouty are known (Spry1-Spry4). The role of the mammalian analogs has not been clearly elucidated although it is believed that human Sprouty-2 (hSpry2) may be an inhibitor of cellular migration and proliferation. Spry2 and Spry4 show considerable sequence homology between human and mouse at the C-terminus of the protein. Significant sequence divergence occurs at the N-terminus. Spry2 appears to be abundant in brain, lung and heart tissue, with lesser amounts found in kidney and skeletal muscle.
Catalog #S5620-03
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 0.1-1ug/ml detects Sprouty2 in RIPA lysates from HeLa and 3T3/A31 cells.
Optimal dilutions to be determined by the researcher.
Included Positive Antigen ControlF4209: 3T3/A31 lysate. Add 2.5ul of 2-mercaptoethanol per 100ul of lysate and boil for 5 minutes to reduce the preparation. Load 10ug of reduced lysate per lane for minigels.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
