High resolution isoelectric focusing of juvenile hormone esterase activity from the hemolymph of Trichoplusia ni (Hübner).
Juvenile hormone esterase (JHE) activity from the hemolymph of larval Trichoplusia ni was analyzed by two different isoelectric focusing (IEF) methodologies. Use of techniques capable of progressively higher resolution split ultimately what appeared at lower resolution to be a single peak into two discrete peaks of JHE activity (pI 5.5 and 5.3). Neither peak was a degradation artifact of the other caused by conditions of IEF.
