Description
PRINCIPLE OF THE ASSAY
This assay employs the quantitative competitive enzyme immunoassay technique. Omalizumab has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled Human IgE and then pipetted into the wells. Anti-Omalizumab Neutralizing Antibody in the sample competitively binds to Omalizumab with the biotin-labeled Human IgE. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Anti-Omalizumab Neutralizing Antibody bound in the initial step. The color development is stopped and the intensity of the color is measured.
Applications
Used for the quantitative determination of Anti-Omalizumab Neutralizing Antibody concentration in serum and plasma.
Detection method
Colorimetric
Sample type
Plasma, Serum
Assay type
Quantitative
Range
156.25 - 10,000 ng/mL

82.6 ng/mL
Precision
Intra-Assay Precision (Precision within an assay): <20%
Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays): <20%
Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.
Recovery
80-120%
Shipping
2-8 ℃
Stability and Storage
When the kit was stored at the recommended temperature for 6 months, the signal intensity decreased by less than 20%. For unopened kits, if you want to prolong the storage time, please store the Standard, Detection A, Detection B and Microplate at - 20℃, the rest reagents should be store at 4℃.
