Challenges of Autofluorescence in Neuroscience

If you have ever imaged biological samples, you have likely encountered autofluorescence. That pesky background coloration you see under the microscope, which can make it difficult to distinguish your actual signal from the noise.1 When you are trying to look for something as delicate as RNA, you don’t want to be hunting for your signal…

Detecting Signal in qPCR: From DNA Binding Dyes to BHQ Probes

A Brief History of Detecting Amplicons The Old Days of Ethidium Bromide In the early 1990s, quantitative (q) PCR was in its infancy, and despite PCR itself already being around for 10 years, there were no easy ways of precisely quantifying the amount of DNA that was amplified in a PCR reaction. In those days PCR…

Modify Your Oligos, Modify Your Experiments

If you’ve ever performed PCR, you’re probably already very familiar with DNA oligonucleotides (or oligos). But did you know that these molecules can do so much more than just act as simple primers? You can add a wide range of modifications to your oligos, which may change the stability, binding, solubility and even visibility, to…

How RNA-FISH Can Complement qPCR, and Vice Versa

In studies of RNA abundance and gene expression, no one technique can answer all of the questions that need to be asked. So it is necessary to use a variety of experimental methods in concert. Two RNA detection and measurement techniques that complement each other well for this purpose are RNA Fluorescence in situ hybridization…

A primer on Probe-based SNP genotyping

Single Nucleotide polymorphisms (SNPs), colloquially pronounced ‘snips’, are the most common type of genetic variation in people. By definition, a SNP represents a single nucleotide variation at a specific location in the genome that is found in more than 1% in the population. For example, a SNP can replace the nucleotide cytosine (C) with an…
