Typical Testing Data/Standard Curve (for reference only)
Intended Uses: This CD19 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Goat CD19. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay: CD19 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-CD19 antibody and an CD19-HRP conjugate. The assay sample and buffer are incubated together with CD19-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CD19 concentration since CD19 from samples and CD19-HRP conjugate compete for the anti-CD19 antibody binding site. Since the number of sites is limited, as more sites are occupied by CD19 from the sample, fewer sites are left to bind CD19-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CD19 concentration in each sample is interpolated from this standard curve.
Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate
Assay Type: Competitive
Sensitivity: 0.1 ng/mL. Goat Cluster of differentiation 19 ELISA Kit or ELISA (enzyme-linked immunosorbant assays) Kits in general, are a valuable research tool for a myriad of applications in a range of scientific settings. Currently, three major types of ELISA formats are used by researchers: sandwich, competitive and indirect. Most commercially available ELISA Kits are sandwich or competitive. Commercially available ELISA Kits contain wells that have been pre-coated with the capture antibody. Please refer to the product manual for the ELISA format of your specific kit. CD19 also interacts with the following gene(s): BTK, CD22, CD79A, CD79B, CD81, CR2, LYN, SYK, VAV1.
