How to increase ct value
Did you know?
The C t value increases with a decreasing amount of template. However, artifacts from the reaction mix or instrument that change the fluorescence measurements associated with the C t calculation will result in template-independent changes to the C t value. Meer weergeven To properly evaluate PCR efficiency, a minimum of 3 replicates and a minimum of 5 logs of template concentration are necessary. The reason for this suggested level of rigor … Meer weergeven Another critical parameter to evaluating PCR efficiency is R2, which is a statistical term that indicates how good one value is at predicting another.
