Gene reporters enable valuable insight into gene expression. The GUS gene reporter system is one of the popular and common plant reporter systems. GUS, is short for glucuronidase, an enzyme in the bacterium E. coli. GUS is a good reporter for plants, as it does not occur naturally, and thus, has a low background. With…
MicroRNAs (miRNA) are short, non-coding RNAs involved in post-transcriptional silencing of gene expression. miRNAs can be associated with exosomes and can function as cancer-specific biomarkers. This, coupled with the fact that they are stable in plasma and serum makes them valuable diagnostic tools, as long as they can be reliably isolated from the serum and…
If efficient cloning is what you are after, you must give Overlap Extension PCR Cloning a go! This restriction enzyme and T4 DNA ligase-free technique is faster, more reliable and easier to troubleshoot than traditional restriction methods. With only two PCR reactions required, you can insert a DNA fragment into a plasmid without spending time…
If you ever used a site-directed mutagenesis kit or ligation-independent cloning, then you also used restriction enzyme Dpn I. But what does it do and more interestingly, why? Restriction enzymes and methylases: the yin and yang of bacteria Usual restriction enzymes, the toolkit of genetic engineering, are one half of the “yin and yang” pair…
They say a magician is never supposed to tell the secret behind his tricks. It’s a good thing then that I am a molecular biologist and not an illusionist. Because once I learn a good trick, I feel the need to spread it like dandelion seeds floating on a breeze. That’s what inspired me to…
When I began a master’s program in 2008, the lab task I hated more than anything was running agarose gels for DNA. Something so simple, ubiquitous, and necessary gobbled up more hours in the lab than I care to remember. Even though we added the DNA stain directly to the molten agarose and didn’t have…
