Synthesis Reagent:

This reagent is used for the synthesis of Canaline-containing peptides. It is a derivative of ornithine, a naturally occurring amino acid with an O-alkyl hydroxylamine side chain that is produced by arginase from Canavanine. Due to its toxicity, by its ability to form oximes with carbonyl-containing biomolecules, it is produced by legumes as protection from herbivores. L- Canaline possesses anti-tumor activity against human acute leukemia T-cells, and as a result is of interest in cancer research. It also possesses antimalarial and antineoplastic properties.

Virology Peptides:

The entire archive of Peptides International Product Spotlights is available here.  The topics range from some of the most popular items we have available to those lesser known ones that still have compelling research applications.  They often are chosen due to recently published articles that feature them.  They are permanently posted here, so read at your leisure!
