Simple BLAST searching is pretty straightforward to many of us. Just plug in your sequence, select the species genome, and hit search! But have you ever wondered what it takes to run a BLAST query using these mammoth-sized (no pun intended!) sequence databases? BLAST searching can produce dozens, hundreds, or even thousands of candidate alignments….
When I was being trained in microbiology as an undergrad, one of the first skills I acquired was the ability to quickly compare and visualize amino acid sequences using BLAST and ClustalW. 15 years later, those two programs have done nothing but improve by expanding the data contained in these databases and simplifying the user…
How to Obtain a Purer PCR Product and Reduce Non-specific Amplification Unless you’ve gotten your hands on some miraculously specific primers, amplification of only your target sequence without non-specific amplification can be very challenging. Thankfully, a clever and surprisingly simple solution is at hand! A Quick Recap of the Basics In PCR, you design your…
BLAST is the most popular bioinformatics online tool. But in order to properly use it, you have to understand that is not just a search query against a database but something far more complicated, and the information you get back far more…precious!
