Linear range of the assay
NettetIf you know your sample is greater than the linear range, or if after performing an assay is outside the linear range, then you would need to dilute the sample. For example, if the unknown sample is expected to have a concentration of 5mg/ml and the linear range of your assay is 0.1-1mg/ml, then the unknown sample needs to be diluted 10 fold so it is … NettetA common method for validating qPCR assays involves the construction of a standard curve, enabling the determination of the efficiency, linear dynamic range, and reproducibility of a qPCR assay. The efficiency of the assay should be 90–105%, the R2 of the standard curve should be >0.980 (or r > –10.990), and the quantification cycle …

Nettet15. jul. 2024 · The infective titers determined with the Incucyte ® approach when compared with the flow cytometry-based assay had a lower standard deviation between replicates and a broader linear range. A major advantage of the method is the ability to obtain titer results in real-time, enabling an optimal readout time. NettetStandard curve range Typically, an ELISA measures protein concentrations in the range of 0.1-1 fmole or 0.01-0.1 ng, however this is dependent on the antibody-antigen interaction. Therefore, a classic …
