Protocols
The most popular reagent for cleavage of peptides from Boc-based resins is anhydrous HF. Of all the cleavage procedures HF appears to be the most versatile and least harmful to a wide variety of peptides synthesized on Boc-based resins.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
