IL-3 (Hematopoietic growth factor, Mast cell growth factor)

The gene IL-3 encodes interleukin 3, a hematopoietic colony-stimulating factor (CSF) that is capable of supporting the proliferation of a broad range of hematopoietic cell types.1 Interleukin-3 (IL-3), a protein of 140 amino acids, is chemically synthesized by means of an automated peptide synthesizer and is shown to have the biological activities attributed to native IL-3.2 The cDNA sequence for murine interleukin-3, one of the colony stimulating factors that regulate haematopoiesis, codes for a polypeptide of 166 amino acids including a putative signal peptide.3 The mouse IL 3 gene is located on chromosome 11.4 The human gene encoding IL 3 is tandemly arrayed on the long arm of chromosome 5.5 The standard product used in this kit is recombinant human IL-3, consisting of 133 amino acids with the molecular mass of 15KDa.\n\nUniProt Number:\nP08700\n\nGene ID:\nIL3\n\nApplications:\nSuitable for use in Western Blot and Immunohistochemistry (Paraffin).\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Handling:\nStore at -20?C for one year. After reconstitution, store at 4?C for one month. Can also be aliquoted and stored frozen at -20?C for long term.\nAvoid repeated freezing and thawing. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
