This Human Complement Receptor 2 (CD21) Rapid ELISA Kit from Innovative Research is intended is a fast ELISA kit, this assay takes less than 1.5 hours to detect Human Cd21/CR2 with <20pg/ml sensitivity. format: 96-well plate with removable strips. Compatible samples: cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). This is a TMB colorimetric sandwich ELISA kit with short assay time and fast experiment set up. Cd21/CR2 tissue specificity: Mature B-lymphocytes, T-lymphocytes, pharyngeal epithelial cells, astrocytes and follicular dendritic cells of the spleen. Strip well format. Reagents for up to 96 tests.

This human CD21 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CD21 has been precoated onto 96-well plates. Standards(CHO, Ile21-71) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CD21 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CD21 amount of sample captured in plate.

Additional Information: The capture antibody is monoclonal antibody from mouse, the detection antibody is polyclonal antibody from goat. Expression system for standard: Complement receptor type 2(CR2), also known as C3DR or CD21, is a protein that in humans is encoded by the CR2 gene. It is mapped to 1q32.2. CR2 is involved in the complement system. It binds to iC3b(inactive derivative of C3b), C3dg, or C3d. CR2 is the membrane protein on B lymphocytes to which the Epstein-Barr virus (EBV) binds during infection of these cells. CR2, together with CD19, CD81, and CD225, forms the B-cell coreceptor complex, which lowers the activation threshold of the B-cell antigen receptor. Genetic variations in this gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9).; Immunogen sequence: 419
