Effect of chain elongation on biological properties of the toxin paralysin β-alanyl-tyrosine.

In hemolymph of insect species, compounds with remarkable properties for pharmaceutical industry are present. At the first line, there were found compounds of low molecular mass, less than 1 kDa. One of such compounds, β-alanyl-tyrosine (252 Da), was isolated from larval hemolymph of some species of holometabolous insects (e.

Mapping the peptide and protein immune response in the larvae of the fleshfly Sarcophaga bullata.

We chose the larvae of fleshfly Sarcophaga bullata to map the peptide and protein immune response. The hemolymph of the third-instar larvae of S. bullata was used for isolation.
