Understand and Troubleshoot PCR with The BitesizeBio Guide to PCR
Over the years, I’ve had my fair share of ups and downs in the lab. The latter quite often centering on a failed or plainly weird PCR experiment.
As I’ve gone on and become ever more fastidious about my lab practices I’ve realized that the majority of these little calamities were perfectly avoidable. In my new e-book, The Bitesize Bio Guide to PCR, I aim to impart much of my hard-earned and entrenched wisdom with readers, who like me, prefer a simple PCR life.
Standard PCR revolutionized our ability to study a small fragment of DNA or RNA by replicating its number thousands-fold. This small leap was only the beginning, however, and paved the way for much bigger and better technology to come our way. Today, while many researchers and clinical services still depend on standard PCR techniques, the majority of us are also seeking highly precise and quantitative solutions, including quantitative real-time PCR (qPCR) and more recently digital PCR (dPCR).
This e-book is here to help you figure out the basic practices that are essential for getting your PCR, qPCR or dPCR experiment right. By focusing on the ‘how to fix’ element, this e-book provides an essential PCR trouble-shooting guide for any student or researcher using PCR in the lab.
And here’s a little sneak preview of the e-book contents:
