Eotaxin BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human Eotaxin in cell culture supernates, serum and plasma (citrate, EDTA).\n\nEotaxin, also known as CCL11, is a potent inducer of eosinophil chemotaxis and is considered as a selective ligand of the CC chemokine receptor 3 (CCR3), which is expressed on eosinophils, basophils, and Th2 lymphocytes.1 Eotaxin is assumed to be involved in eosinophilic inflammatory diseases such as atopic dermatitis, allergic rhinitis, asthma and parasitic infections.2 The gene maps to chromosome 17 and is expressed constitutively at high levels in small intestine and colon, and at lower levels in various other tissues. The deduced mature protein sequence is 66% identical to human monocyte chemoattractant protein-1, and 60% identical to guinea pig eotaxin. Recombinant human eotaxin produced in insect cells induces a calcium flux response in normal human eosinophils, but not in neutrophils or monocytes.3 The human eotaxin gene is cloned and found to be 61.8 and 63.2% identical at the amino acid level to guinea pig and mouse eotaxin.4\n\nAssay Range:\n31.2pg/ml-2000pg/ml\n\nSensitivity:\n< 2 pg/ml\n\nCrossreactivity:\nThere is no detectable cross-reactivity with other relevant proteins.\n\nUniprot ID:\nP51671\n\nEntrez Gene ID:\n6356\n\nKit Components:\n96-well plate pre-coated with anti-Eotaxin, Human\nLyophilized recombinant Eotaxin, 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.
