Human Complement Receptor 2 (CD21) ELISA Kit

Cat. No.: EJ1514892

GRAU & PUREZA BioReagent

Visão geral

This kit employs the sandwich enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with a capture antibody specific to Human CD21. Following this, the sample, standards, a biotin-conjugated detection antibody, and an HRP (horseradish peroxidase)-labeled conjugate are added sequentially to the wells. The procedure involves incubation and wash steps between each addition. For detection, TMB substrate is used. TMB yields a blue color in the presence of the peroxidase activity of HRP. The reaction is then stopped with an acid solution, which converts the blue color to a final yellow color. The intensity of the yellow color is directly proportional to the concentration of Human CD21 present in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader. Finally, the concentration of the target analyte in the sample is calculated based on the standard curve generated from the standards.
