Naturally occurring analogs of Lymantria testis ecdysiotropin, a gonadotropin isolated from brains of Lymantria dispar pupae.


Lymantria testis ecdysiotropin (LTE) was isolated from the most prominent peptide peak corresponding to an active fraction obtained by high pressure liquid chromatographic (HPLC) separation of a homogenate of 13,000 Lymantria dispar pupal brains. In this work we examined the other active fractions from this separation as well as a second HPLC separation of… (More)
