SF-20, Recombinant, Mouse (IL-25)

Murine SF20 is a bone marrow stroma-derived growth factor.SF20 is expressed in bone marrow, spleen stroma cells, resting mononuclear cells, resting CD8+ and CD19+ cells and activated CD8+ T cells and has been shown to bind to the surface of cells expressing the receptor TSA-1 (Thymic shared Ag-1).Among its biological activities, SF20 stimulates the proliferation of FDCP2 cells (a mouse factor-dependent hemopoietic cell line) and mouse lymphoid cells.Recombinant murine SF20 is a 15.8kD protein containing 143 amino acid residues.\n\nAA Sequence:\nMVSEPTTVPF DVRPGGVVHS FSQDVGPGNK FTCTFTYASQ GGTNEQWQMS LGTSEDSQHF TCTIWRPQGK SYLYFTQFKA ELRGAEIEYA MAYSKAAFER ESDVPLKSEE FEVTKTAVSH RPGAFKAELS KLVIVAKAAR SEL\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.
