WitrynaThe universal way is to plot Cq as a function of the log (base 10) of the actual concentration of the template. Independent of whether your dilution was 1:5 or 1:10, the slope should be -3.32. If... WitrynaTo accurately determine the efficiency of a PCR reaction, a 5-log dilution series must be performed. A slope of –3.3 ±10% reflects an efficiency of 100% ±10%. A PCR reaction with lower efficiency will have lower sensitivity. R2 value

WitrynaTypically, 1% of starting chromatin is used as input. To calculate percent input: * Note: For example, if the starting input fraction is 1%, then a dilution factor (DF) of 100 or 6.644 cycles (i.e., log2 of 100) is subtracted from the Ct value of diluted input. Fold Enrichment Method Witryna* Note: For example, if the starting input fraction is 1%, then a dilution factor (DF) of 100 or 6.644 cycles (i.e., log2 of 100) is subtracted from the Ct value of diluted input. Fold Enrichment Method This normalization method is also called 'signal over background' or 'relative to the no-antibody control'. With this method, the ChIP signals ... Witryna5 lip 2016 · % Input = 2 (- Ct (Ct [ChIP]— (Ct [Input]—Log2 (Input Dilution Factor)))) [ 24 ]. As a negative control, we used the immunoprecipitate products from the normal mouse IgG group.
