PCR, qPCR and qRT-PCR

An Introduction to MassTag PCR

New ways to perform PCR emerge all the time. This speaks for the speed of technological advances, and reflects the ongoing need to keep up with fast-moving research. We all know that PCR’s main purpose is to amplify a stretch of nucleic acids based on sequence-specific primers. Nowadays, a wide range of PCR techniques exist,…

Faster PCR Optimization

So, you’ve designed PCR primers to amplify your sequence of interest, and you’re ready to go.  But unless you have a never-ending supply of template, polymerase, and a thermocycler with a gradient function—not to mention a hefty dose of time and patience—you probably don’t want to spend the next week finding the perfect conditions for…

The Obligate qPCR Standard Curve

At first sight, real-time PCR looks like a very simple technique—very straightforward. Also, when it’s optimized, real-time PCR leads to interesting results. However, to obtain consistent and accurate results reflecting the reality, good controls are crucial for SYBR qPCR.  One of these controls is the qPCR standard curve to check for the efficiency of your primers. Efficient Primers…

DNA Shuffling Like a Pro

DNA shuffling uses PCR technology in a very creative way. It allows you modify your protein to make a new protein you want. You can evolve proteins in microcentrifuge tubes on your very own lab bench. Isn’t that fantastic? DNA shuffling is also a very powerful technique for directed molecular evolution. W. Stemmer first used…
