qPCR Efficiency Determination ProtocolOptimization of qPCR conditions is important for the development of a robust assay. The two main approaches are optimization of primer concentration and/or annealing temperatures. Multiplex Real-Time PCRMultiplex qPCR employing probe-based chemistries is a demanding appl...

(primer 200–900 nM, probe 100–500 nM). When loading qPCR protocol onto the real-time instrument, be sure to select the appropriate optical channels, as some instruments have a single channel recording mode that would prevent multiplex data collection and analysis. For ROX-dependent instruments...
A 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...
This study represents the critical first step to establish a standardized RT-qPCR protocol for the functional genomics research in a ladybeetle C. maculate. Furthermore, it lays the foundation for conducting ecological risk assessment of RNAi-based gene silencing biotechnologies on non-target organisms...
