pI Value

Organism Comment pI Value Maximum pI Value
Helicoverpa zea the major bands for HzTrypsin-C focus around pI 9, the minor band for HzTrypsin-C focuses around pI 7. HzTrypsin-S has threee major species and a minor band in the 9-10 area. Although HzTyrpsin-S focuses at three different isoelectric points, it appears to relate to a single trypsin gene
