Guidelines for Primer Design and Tm Range Acceptable with the Luna qPCR Products Guidelines for Primer Design and Tm Range with Luna qPCR Products When working with Luna qPCR , designing the right primer is crucial for accurate and efficient amplification. Whether you're targeting cDNA synthesis , optimizing multiplex reactions , or ensuring specificity, following best practices will save you time and improve results. Let's break down everything you need to know about primer design , amplicon length , and Tm optimization for Luna qPCR. 1. Optimal Amplicon Length for qPCR For the best performance with Luna qPCR , aim for short amplicons between 70–200 bp . Why? Shorter fragments amplify more efficiently, reducing the chance of errors and improving sensitivity. 70–200 bp is the sweet spot for high-efficiency amplification . Balanced GC content (40–60%) prevents secondary struc...

2-step PCR vs. 3-step PCR 2-Step vs. 3-Step PCR: Differences, Advantages, and Best Practices 2-Step vs. 3-Step PCR: Differences, Advantages, and Best Practices Introduction Polymerase Chain Reaction (PCR) is a fundamental technique in molecular biology, widely used for amplifying DNA sequences. Over the years, researchers have developed different PCR protocols to optimize amplification efficiency and specificity. Among these, 2-step PCR and 3-step PCR are two commonly used methods. The traditional 3-step PCR consists of three distinct temperature phases: denaturation, annealing, and extension. In contrast, 2-step PCR merges the annealing and extension steps into a single phase. The choice between these two methods depends on various factors, including primer melting temperature (Tm), DNA template complexity, and enzyme selection. In this article, we will explore the differences between 2-step a...
