Insights into qPCR: Protocol, Detection Methods, and Analysis
Nov 8, 2023 — qPCR, also known as real-time PCR, is an extension of traditional PCR, where DNA amplification over time is quantitated by measuring fluorescence from dyes intercalating into nascent DNA strands or by cleavage of target-specific probes. Therefore, the method combines detection with amplification, providing researchers with crucial data in real ...
Optimizing PCR: Proven Tips and Troubleshooting Tricks
Feb 23, 2024 — Template DNA. Template amount, source, and secondary structures or GC-rich regions may affect the reaction. 7. The amount of template depends on the DNA copy number. For a standard PCR reaction with 25-30 cycles, roughly 10 4 copies of the template DNA are sufficient to generate a detectable amount of PCR product. 7; The DNA required for a given reaction also depends on the source.
