Orthogonal side chain protecting groups, particularly for Fmoc-based solid phase peptide synthesis, are growing not only in diversity, but also in popularity. These protecting groups enable post-synth...
Disulphide rich peptides have gained significant attention recently due to their incredible biological stability and tolerance to epitope grafting. This class of peptides is often folded in solution, ...
When it comes to synthesizing a peptide, the first thing that comes to mind is the number of stoichiometric equivalents to use. Sometimes that number is as few as 1.5, sometimes it’s as high as 20! Bu...
In my role as a peptide application scientist, I have had the pleasure of working with many groups that are venturing into the world of peptides for the first time. Although it seems rather straightfo...
Would you ever consider an alternative to reversed- phase HPLC to purify your synthetic peptides? It seems like a silly question, right. And like many of you, I literally laughed at my Product Manager...
More and more we are seeing groups that would historically undertake only traditional organic chemistry or possibly biochemistry/biology, incorporate peptides into their research programs. While this ...
There are many techniques available to analyse and identify synthetic compounds that we are taught in the first few years of our chemistry education. While tools like NMR spectroscopy, IR spectroscopy...
"50% of my time as a Ph.D. was spend baby-sitting columns," stated Dr. László Kürti during our interview in February. Keep reading to find out more about how his team was able to increase their produc...
Your choice of sample loading technique can, and likely will, affect the separation and purity of your targeted compound. While liquid loading is easy and often fit for purpose, it can provide some is...
Purifying polar organic compounds can be very challenging. In a previous post I have discussed using reversed-phase flash chromatography to retain and purify ionizable and ionic compounds. My colleagu...
