CTLA4 BioAssay(TM) ELISA Kit, Mouse

Sandwich ELISA quantitative detection kit for Mouse CTLA4 in cell culture supernates, serum, plasma (heparin).\n\nCTLA-4(Cytotoxic T-Lymphocyte Antigen 4), also known as CD152 (Cluster of differentiation 152), is a protein receptor that down regulates the immune system. CTLA4 is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and transmits an inhibitory signal to T cells. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Blockade of CTLA4 expression in vitro augmented HIV-specific CD4-positive T-cell function.\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:\nP09793\n\nEntrez Gene ID:\n12477\n\nKit Components:\n96-well plate pre-coated with anti-CTLA4, Mouse\nLyophilized recombinant CTLA4, Mouse 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.
