Description

PRINCIPLE OF THE ASSAY This assay employs the quantitative sandwich enzyme immunoassay technique. Atezolizumab has been pre-coated onto a microplate. Samples or standards are pipetted into microwells and Anti-Atezolizumab will be captured by immobilized Atezolizumab. After washing away any unbound substances, a biotin-labeled Atezolizumab is added to the wells. 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 proportion to the amount of Anti-Atezolizumab 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-Atezolizumab concentration in serum and plasma.

Detection method

Colorimetric

Sample type

Plasma, Serum

Assay type

Quantitative

Range

1.56 - 100 ng/mL

Sensitivity

0.78 ng/mL

Precision


Intra-Assay Precision (Precision within an assay): <10%

Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays): <15%

Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.

Data Image


  • Experiment Example
    CALCULATION OF RESULTS
    Average the duplicate readings for each standard and sample. Construct a standard curve by plotting the mean absorbance for each standard on the Y-axis against the concentration on the X-axis and draw a best fit curve through the points on the graph. The data may be linearized by plotting the log of the Anti-Atezolizumab concentrations versus the log of the O.D. and the best fit line can be determined by regression analysis. This procedure will produce an adequate but less precise fit of the data. If samples have been diluted, the concentration read from the standard curve must be multiplied by the dilution factor.
