Cat no: 143340

GDF-11, Recombinant, Human (Growth/Differentiation Factor-11, BMP-11)

GDF-11 is a myostatin-homologous protein that acts as an inhibitor of nerve tissue growth.GDF-11 has been shown to suppress neurogenesis through a myostatin-like pathway, which involves arrest of progenitor cell-cycle in the G1 phase.Similarities between myostatin and GDF-11, which are 90% identical in their amino acid sequence, suggests that the regulatory mechanisms responsible for maintaining proper tissue size during neural and muscular development might be the same.Recombinant human GDF-11 is a 25.0kD disulfide-linked homodimer containing two 109 amino acid polypeptide chains. It is highly homologous to myostatin/GDF-8 sharing 90% amino-acid sequence identity.\n\nBiological Activity:\nThe ED50 was determined by its ability to inhibit induced alkaline phosphatase production by ATDC-5 chondrogenic cells. The expected ED50 for this effect is 0.08-0.10ug/ml.\n\nAA Sequence:\nNLGLDCDEHS SESRCCRYPL TVDFEAFGWD WIIAPKRYKA NYCSGQCEYM FMQKYPHTHL VQQANPRGSA GPCCTPTKMS PINMLYFNDK QQIIYGKIPG MVVDRCGCS\n\nCrossreactivity:\nMouse\n\nQuality Control:\nVerified by N-terminal and Mass Spectrometry analyses (when applicable).\n\nEndotoxin:\n<0.1ng/ug of protein (<1EU/ug).\n\nProtein Content:\nVerified by UV Spectroscopy and/or SDS-PAGE gel.\n\nStorage and Stability:\nStore lyophilized products at -20 degrees C. For reconstituted solutions of most products, we recommend short-term storage at 4 degrees C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20 degrees C. Additional freeze/thaw cycles may cause some denaturation of the protein.
