IL1RL1/ST2 BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human IL1RL1/ST2 in cell culture supernates, serum and plasma (heparin, EDTA).\n\nInterleukin 1 receptor-like 1, also known as IL1RL1 or ST2, is a protein that in humans is encoded by the IL1RL1 gene. The protein encoded by this gene is a member of the interleukin 1 receptor family. Studies of the similar gene in mouse suggested that this receptor can be induced by proinflammatory stimuli, and may be involved in the function of helper T cells. TL1RL1 is necessary for endotoxin tolerance and, by inhibiting TLR responses, enhances Th2 responses. This gene, interleukin 1 receptor, type I (IL1R1), interleukin 1 receptor, type II (IL1R2) and interleukin 1 receptor-like 2 (IL1RL2) form a cytokine receptor gene cluster in a region mapped to chromosome 2q12.\n\nAssay Range:\n156pg/ml-10,000pg/ml\n\nSensitivity:\n< 10 pg/ml\n\nCrossreactivity:\nThere is no detectable cross-reactivity with other relevant proteins.\n\nUniprot ID:\nQ01638\n\nEntrez Gene ID:\n9173\n\nKit Components:\n96-well plate pre-coated with anti-IL1RL1/ST2, Human\nLyophilized recombinant IL1RL1/ST2, 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.
