Caption: Tree frog research. Male biologist using a pipette during research on Phyllomedusa bicolor, an Amazon tree frog. This frog produces peptides (small chains of protein-forming amino acids) from its skin glands. Some of the peptides have pharmaceutical properties, namely as painkillers (dermorphins) and antibiotics (dermaseptins). Photographed at the Peptide Bioactivation Laboratory in the Institut Jacques-Monod, France.
