IL-7, Recombinant, Rat (Lymphopoietin 1(LP-1), pre-B cell factor)

IL-7 is a hematopoietic growth factor which affects primarily early B and T cells.Produced by thymic stromal cells, spleen cells and keratinocytes, IL-7 can also co-stimulate the proliferation of mature T cells in combination with other factors such as ConA and IL-2.Human and murine IL-7 is cross-species reactive.Recombinant rat IL-7 is a 15.0kD protein containing 130 amino acid residues.\n\nBiological Activity:\nThe ED50 was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is ~2.0ng/ml, corresponding to a specific activity of ~5x10e6 units/mg.\n\nAA Sequence:\nMDCHIKDKDG KAFGSVLMIS INQLDKMTGT DSDCPNNEPN FFKKHLCDDT KEAAFLNRAA RKLRQFLKMN ISEEFNDHLL RVSDGTQTLV NCTSKEEKTI KEQKKNDPCF LKRLLREIKT CWNKILKGSI\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.
