产品：小鼠CTLA4ELISA试剂盒 货号：EK0717 Description CTLA4 (Cytotoxic T-Lymphocyte Antigen 4), also known as CD152 (cluster of differentiation 152), is a receptor protein 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 augments HIV-specific CD4-positive T-cellFunction. ScienCells mouse CTLA4 ELISA kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Mouse CTLA4-specific polyclonal antibodies are pre-coated onto 8 x 12 divisible strips. The mouse-specific detection polyclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes to yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of mouse CTLA4 in the sample that is captured on the strips. Product Use This product is for research use only.
