GM-CSF BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human GM-CSF in cell culture supernates, serum and plasma (heparin, EDTA, citrate).\n\nGranulocyte-macrophage colony-stimulating factor (GM-CSF) is also symbolized CSF2. Human GM-CSF is a glycoprotein that is essential for the in vitro proliferation and differentiation of precursor cells into mature granulocytes and macrophages. The human cDNA clones contain a single open-reading frame encoding a protein of 144 amino acids with a predicted molecular mass of 16,293 daltons and show 69% nucleotide homology and 54% amino acid homology to mouse GM-CSF. The gene for human GM-CSF appears to exist as a single-copy gene.1 Human GM-CSF is a 22,000-dalton glycoprotein that stimulates the growth of myeloid progenitor cells and acts directly on mature neutrophils. The GM-CSF gene is localized by somatic cell hybrid analysis and in situ hybridization to human chromosome region 5q21-5q32, which is involved in interstitial deletions in the 5q- syndrome and acute myelogenous leukemia.2 A complementary DNA for the T lymphocyte-derived lymphokine, GM-CSF has been cloned, and recombinant GM-CSF protein has been expressed in yeast and purified to homogeneity. This purified human recombinant GM-CSF stimulates peripheral blood monocytes in vitro to become cytotoxic for the malignant melanoma cell line A375.3 \n\nAssay Range:\n15.6pg/ml-1000pg/ml\n\nSensitivity:\n< 1 pg/ml\n\nCrossreactivity:\nThere is no detectable cross-reactivity with other relevant proteins.\n\nUniprot ID:\nP04141\n\nEntrez Gene ID:\n1437\n\nKit Components:\n96-well plate pre-coated with anti-GM-CSF, Human\nLyophilized recombinant GM-CSF, Human standard, 10ng/tube, 2Ea\nUSB Cat No Kit Component\n143696 Avidin-Biotin-Peroxidase Complex (ABC), 130ul (1:100 dilution)\n143697 Sample diluent buffer, 30ml\n143698 Antibody diluent buffer, 12ml\n143699 ABC diluent buffer, 12ml\n143700 TMB color developing agent, 10ml\n143701 TMB stop solution, 10ml\n\nStorage and Handling:\nStore at 4 degrees C for 6 months, at -20 degrees C for 12 months.
